Does human life have innate value over that of other animals?



Does human life have innate value over that of other animals? If so, why? And is it wrong to murder another human, but morally permissible to hunt or fish?

2The strong and dedicated opinion of each individual about the issue with respect to themselves leads to a near-unanimous collective opinion about the issue. In other words, if you answer it for yourself you have answered it philosophically. – Peter - Reinstate Monica – 2019-02-18T08:18:38.443

4If you want to know if there's some principle written into the fabric of the universe that logically impels us to value human life above animal life, the answer is no. However, these options both have consequences that cannot be avoided. If you posit that human life is more valuable, you can't treat people as if they were no better than animals. If you reject that humans are more valuable, you have no grounds to object if someone treats you that way. – EvilSnack – 2019-02-19T02:43:51.213

@EvilSnack If you posit that human life is more valuable, then you can treat animals as less valuable. If you reject that humans are more valuable, then you shouldn't treat animals as less valuable. Either way there's no a priori reason to assume we can treat humans badly. Either way we can object to our own poor treatment. – sfmiller940 – 2019-02-25T23:46:34.273

@sfmiller: yes, we can do these noble things, but that is not my point. My point is that there are consequences to the choice made; we choose the consequences our ideas will have by choosing our ideas. – EvilSnack – 2019-02-26T01:37:46.617



Social contract

One aspect (not the only valid aspect, but the one I'll be covering here) of looking at this is from the social contract angle. In essence, since we live in communities together with other humans (and have done so as long as homo sapiens exist) it makes sense to agree to avoid killing each other in most circumstances (e.g. capital punishment, or religious sacrifices, or war) - defining any other killing as murder, and defining murder as Very Bad. It's just a very practical thing to do; if we establish social norms that I won't kill you and you don't kill me, then we're usually both better off than before. And at least part of the murder prohibition certainly is based on this aspect.

While the boundaries of social contract are in general arbitrary - there certainly can be social contract that highly values the lives and rights of one "tribe" (for a very, very wide interpretation of "tribe") and disregards the lives and rights of everyone else, there's still a major difference regarding animals; it makes sense to extend the social contract to all other people surrounding you (including all other "tribes"), because you'd want them to follow that social contract regarding yourself. It's not automatic (there are plenty nasty examples in history, including quite recent history), but in general that's a solid trend. With animals, on the other hand, such social contract isn't possible, because it can't be mutual, there's no reciprocity, they aren't members of our society and can't be because they lack the capacity to do so.

Our relationship with animals is inherently asymetrical. Bears can't peacefully join our society and obey its rules even if we'd grant them full human rights, and salmon won't be productive members of our society if they'd have equal rights, nor would they pose some threat to us if we'd not agree to their demands, so it's not in our interests to treat them as if they had equal rights and value - contrasting this with all the different groups of people whose lives had (de facto) less value in various societies just a few centuries ago, and the way how these differences have faded - mostly because all those people actually are (or can be) valuable members of societies and it's good for me and everyone else if they're included in our social contract.

1One thing I do wonder about is that animals don't always live in communities, and even the most solitary of animals do not tend to kill their own kind wantonly. They may do so in cases of necessary survival (starvation cannibalism, fighting over survival resources, or fighting to get to mate with the female), but even solitary animals show a distinct avoidance of killing their own kind. – Flater – 2019-02-15T07:56:34.760

2Yet at the same time, humans have a tendency to kill other humans far more than probably every animal (including insects) combined. We're kind of messed up actually. – Nelson – 2019-02-15T08:40:16.787

3@Nacht Handicapped people are generally in charge of a tutor which are responsible for their charge. And we commonly agree that these people would hold the contract if they were able. But if you take the case of criminals (whatever the reason, they could be handicapped too) we have no problem taking their rights (and in some places, their lives) away if they do not follow the contract. – Echox – 2019-02-15T09:05:34.223

5@Flater this seems like an idealized view of animals - IMHO this is mostly explained by the fact that it makes sense to avoid unnecessary fights between equally sized opponents, as it's costly and risky to your own life. One illustrative example may be the practice of infanticide that's well documented to happen in certain situations by primates, lions, etc - animals will systematically kill their own kind if it the fight is unequal enough to not pose a threat to themselves, and this is not limited to necessary survival. – Peteris – 2019-02-15T13:37:20.897


@Flater for a different perspective, is a recent event that may be relevant - and it's not an isolated case, it's standard practice to "evaluate compatibility" of prospective mates for such animals, because otherwise it's quite likely that they'll simply kill one another when meeting.

– Peteris – 2019-02-15T13:40:28.997

@Peteris: Being able to pass on your genes falls under the category of survival in my opinion, albeit a more long-term oriented goal. But I can see how that's debatable. – Flater – 2019-02-15T13:42:10.480

@Flater sure, there's a reasonable evolutionary reason why this kind of behavior exists in these animals. However, from the "innate value of life" perspective, if we're comparing animals and people, the argument of "being able to pass on your genes (instead of the other guy)" would equally well justify both household murders (e.g. jealousy) and systematic genocide of ethnic groups. For humans we would say that such acts mean "killing their own kind wantonly"; sure, there's some personal benefit, but it's very different from immediate necessary survival e.g. self-defence or dire starvation. – Peteris – 2019-02-15T13:47:47.710

6@Nacht That's a good point; and, yeah, it does seem to be the case in practice. When defining "human" in broad terms, we might grant personhood to fetuses, people in comas, those with severe mental/emotional handicaps, very elderly people, etc.; but, in practice, all such individuals tend to suffer treatment far worse than what we'd expect a "human" to otherwise receive, with their personhood discounted for the sake of other interests. The model posed by this answer does seem to have predictive power. – Nat – 2019-02-15T13:53:00.907

@J.G. As I tried to specify in the first sentence of the answer, no, neither I nor social contract theory implies that there are no other moral constraints nor that only social contracts give us rights. It gives grounding for a major part of the situation, one that has explanative power about why things are the way they are, but it's not trying to be an all-encompassing moral framework - I see it more of a descriptive approach instead of a prescriptive one, an is-vs-ought separation; a tool for looking into why we have the morals that we actually have instead of what morals we "should" have. – Peteris – 2019-02-15T15:57:40.770

@Echox Many people in fact do have a problem with taking away the rights (and lives) of criminals. – Nacht – 2019-02-15T19:07:11.277

@Nat,Nacht personhood for people with handicaps is also a somewhat recent development. Spartan society infamously sacrificed infants deemed unfit, which I assume covered visible handicaps. – csiz – 2019-02-15T21:49:20.010

@Nacht We're talking common human practices here, not opinions on what should be. And even though some country decided (very) recently to stop killing criminals, removing the right of freedom (as putting in prison) is something that most people agree on even now. – Echox – 2019-02-15T22:06:13.790

1I'm reminded of the fact that incidents on pig farms involving the pigs killing and eating someone are not at all uncommon. Don't feel bad about eating the pig; given half a chance it would just as well eat you. – AJMansfield – 2019-02-15T23:28:11.933

2@Echox "Handicapped people are generally in (the) charge of a tutor..." That's a very bad ableist statement. I know handicapped people who would have no problem driving their wheelchair straight into you for making such a statement. – gnasher729 – 2019-02-16T12:32:28.900

5@AJMansfield I don't know what personal experience of pigs (if any) you have, but from my own experience they are at best complete psychopaths and at worst both very intelligent and totally malevolent. The first rule of pig farming is "never turn your back on a pig," for good reasons! – alephzero – 2019-02-16T18:06:50.860

You have the situation entirely backwards. It's not that we give humans special privileges but that we don't try to engineer the interactions of animals the same way we try to engineer the interactions of humans. That is, we exempt animals from having to comply with human-created rules because of humility and basic sanity.

Think about what we do when a bear eats a human. Now imagine if we tried to do the same thing if a bear ate a salmon or a deer. We would wind up taking complete human dominion over bear society in a way that doesn't make any sense at all.

If a bear can eat a salmon with impunity, why can't a human? Are humans specially of lower worth and entitlement to eat salmon than bears? Where would that come from? Why would humans be an exception here?

The right question is where would we get the right to force the societies of other animals to play by human rules that don't make any sense in that context? And why should humans be uniquely prohibited from benefiting from other species?

The difference is not being a human animal vs. being a non-human animal, but being a moral agent vs. not being a moral agent. All moral agents are humans (as far as we know), but not all humans are moral agents.

– unor – 2019-02-17T16:04:47.190

2@unor: All moral agents are humans - really? Did you never see a (video of) a dog feeling guilty? Moreover, how do you know what happens in the minds of any non-human being? How can you be sure about the moral values of fish, birds, mamals etc? Who decided that humans are superior (in any way)? Humans! That is plain ego - no morals, no science. – virolino – 2019-02-18T12:03:57.247

@virolino: a dog feeling guilty - I’m not sure if this behavior counts as moral agency, but I’m not making a point about whether or not certain non-humans have this (as far as I know, it’s consensus that non-humans don’t have this trait, but it’s of course under debate), I just state that only moral agents can be held accountable. --- moral values - I didn’t speak of moral value. In my opinion, all sentient beings have moral value.

– unor – 2019-02-18T17:20:35.953

While fish and birds are unlikely to have any (or at least many) moral values, higher primates absolutely do and it can be incredibly sophisticated. – forest – 2019-02-19T00:58:32.927

4@virolino a dog's ability to display humiliation is not the same as actually feeling moral guilt. – David – 2019-02-19T02:22:34.417

@David: so you claim that it is guaranteed that (e.g.) dogs cannot feel moral guilt? I was merely stating that the display of a feeling may have a reasoning in the dog's mind. – virolino – 2019-02-19T05:38:22.900

@unor: "moral agents can be held accountable" - by who? by humans of course (I assume). And who nominated the humans to be the "judges"? (sorry, I do not have a more suitable word). Somehow, this reasoning follows (loosely) the pattern "Humans are right because they are humans". – virolino – 2019-02-19T05:42:14.460

2@virolino: The judges are not humans, but morals/ethics. When a human, who is not a moral agent, kills someone for fun, this human didn’t act immorally. But when this human is a moral agent, he acted immorally. And (most, if not all?) animals would fall into the first camp: their actions aren’t morally wrong or right, these categories don’t apply (just like they don’t apply to human babies, or certain mentally disabled humans). You could say moral agency is a burden. – unor – 2019-02-19T07:35:37.680

"When a human, who is not a moral agent, kills someone for fun, this human didn’t act immorally." - I must admit, that is a very original point of view. How do(es) morals / ethics judge in the absence of humans? – virolino – 2019-02-19T07:38:34.450

@virolino It's simply a fact that moral agents can be held accountable. And it's simply a fact that moral agents are capable of holding things accountable. As far as I know, nobody is arguing that dogs should hold people accountable or that people should hold dogs accountable for violating their rights, and such an argument would lead to obviously silly results. Moral agents are the only things that we can hold accountable and only moral agents can hold things accountable. It might be that in some imaginable future this isn't the case, but it is the fact of the reality we live in now. – David Schwartz – 2019-02-19T22:21:10.043

The problem with moral agency in Animals is its completely speculatory. We don't know if the dog is feeling guilty, or if the dog has simply worked out that when theres a poop on the floor, humans behave aggressively. Guilt is a moral sensation. Fear is something much more primitive. I think Peter Singer is on point with this one. If you are going to derive a moral position from mental states, base it on what we can prove; Suffering and the lack thererof, being the mental state he builds his animal philosophy off (After all, he's a Utilitarian) – Shayne – 2019-02-20T08:32:40.980


IMO your question addresses an important ethical problem. First one can ask:

Does human life have indeed innate value over that of other animals?

In my opinion, the answer is no. Human life does not have such superior value. Because values do not exist in nature. Instead they result from our decision to attach respect and esteem to certain objects or to a certain behavior or attitude.

Of course, in ethics this decision often results from our innate feelings or more precisely: from the empathy we feel for humans or animals similar or close to ourself. We feel empathy with the members of our family, but we do not feel empathy with an insect.

As a consequence, in recent years a movement developed to generalize our human centered ethics to a system of ethics which also includes animals. A proponent of this discipline is Peter Singer. For a first information see

3There are many difficulties with a system of ethics that places animal life at the same innate value as human beings. To do so morally equates butchers with mass-murderers. It also poses the same issues as abortion ethics - where do you morally draw the line? Is it intelligence? And if it is intelligence, then human lives are innately more valuable than animal lives. If it's not intelligence and it's some other quality, which quality is it? Size? A nervous system? When is it murder? Where does the boundary exist? Singer himself argued that this was not exactly clear. – Stephen – 2019-02-18T07:07:34.507

3Yes we don't care about insect, but let's face it: most of us don't care about most others. Do you know a lot of people caring about the Yemenites, right now? – JinSnow – 2019-02-18T10:40:28.760

3@JinSnow I agree with you: The scope of empathy are people or animals close to us. – Jo Wehler – 2019-02-18T10:49:34.197

Stephen. Yes, and Singer does make that equasion. Singer bases his philosophy on the capacity for suffering, and since we can prove animals can suffer, he doesn't see much value in placing human suffering over animal suffering. Singer is consistent about this, and occasionally it leads to some "WTF" type conclusions. My take is reading singer, those WTF conclusions acts a bit like Kants "lying to burglars" thing. Singer might think its an extreme but valid example, but you could also argue it represents a limitation of that line of reasoning. (But you should be able to argue why its invalid!) – Shayne – 2019-02-20T08:37:45.923


Innate or intrinsic value is a kind of value such that when it is possessed by something, it is possessed by it solely in virtue of its innate or intrinsic properties. (Ben Bradley, 'Two Concepts of Intrinsic Value', Ethical Theory and Moral Practice, Vol. 9, No. 2 (Apr., 2006), pp. 111-130: 112.)

To say that human beings have innate or intrinsic value, then, is to hold that all humans and only humans, and therefore no non-human animals, possess the relevant properties.

It is reasonable to ask (a) what these properties are, (b) what is it about them that confers innate or intrinsic value, and (c) what axiological epistemology is available to us to determine the existence and nature of such properties.

I'm not aware of any theory that delivers credible candidates for (a) - (c).

It is one thing intrinsically to value all and only human beings - any form of subjectivism can do that. This is merely an attitudinal matter. It is quite another to say that objectively all and only human beings have innate or intrinsic value. That is a truth-claim and I don't see how it can be made good. I am open to rational suasion, however.

Would you find it more valid that "humans must value all and only human beings on account of their intrinsic value, but animals may kill us as they are able without guilt"? – elliot svensson – 2019-02-18T22:38:40.433

Animals (non-human) will kill us without guilt; it does not follow that they should be allowed to do as they are inclined simply because they act without guilt. A black mamba kills without guilt; that does not mean that it should without preventive measures be allowed to approach a baby. – Geoffrey Thomas – 2019-02-19T08:48:25.163

I'm not suggesting to allow black mambas to do what they really want to do with babies, but that if one does, and (let's say) it returns to its cage in a zoo, it would be nonsense to put that individual mamba on trial, to find it guilty of killing a baby, and to execute it. Instead we would improve our safety stuff so that it doesn't happen again. – elliot svensson – 2019-02-19T15:08:49.267

Religion and philosophy are of course not the same thing, but there is a lot that overlaps, and given that for a lot of people in the world, religion has a profound effect on their personal philosophy, I think this answer is important, and deserves to be listed among the other answers.

I won't go on and on defending it philosophically, as it rests on belief in religion in general, but it really deserves to at least be mentioned and understood.

Christianity and Judaism (and certain sects of Islam?) teach that human beings were created in the Image of God, the imago dei. If this doctrine is true, then it follows directly that there is an intrinsic value placed on human beings.

This is a very complex theological doctrine that pervades how we think about and treat other human beings. It is very much ingrained in Western thinking. It has historically been a motivation for much social change.

According to this view, animals, however, were not created in the Image of God, and as such, do not have the same intrinsic value as human beings. It's that simple.

Note however, that this does not mean that mistreatment of animals is morally okay according to religious doctrine. While not bearing the Image of God, they are part of God's creation that humans are supposed to look after and care for.


Also note that this view is not restricted to people who hold a literal interpretation of Genesis 1. Many believers of the Torah are happy to take Genesis 1 as theological/moral teaching, rather than as scientific/historical teaching. This still leaves many important doctrines to be gleaned from Scripture, including the doctrine of the Image of God. This begs the question, if humans evolved from animals in ages past, when did the Image of God enter the picture? Who knows.

Why does human life have innate value over that of other animals?

In my opinion, you just answered your own question. Observe:


If you want the why of it answered in a more detailed and analytical sense, neuroscience research for xenophobic aggression in mammals or fauna in general is probably your best avenue. Here's a paper that reviewed it for Naked Mole Rats:

First, because humans write the rules we use, and we're not entirely disinterested. It would be awkward to make it illegal to kill other animals in general, but we're generally better off treating the killing of other humans as a generally bad thing.

Second, we maintain a moral boundary by treating humans as moral actors, but not other animals. We hold humans responsible for their own actions, but treat actions of other animals as acts of nature. We're then saying that killing a moral actor is different from killing something natural without moral sense.

With reference to Geoffrey Thomas' excellent answer, I propose a narrowing:

It would be difficult indeed to make a universal claim that humans have intrinsic or innate value. But I believe that this is unnecessary; after all, are we attempting to find a bear or jaguar guilty for killing a human?

Instead, I would say that humans and only humans have innate value, and that must be respected by all humans. But other animals that harm humans do not become guilty for their actions, and so in the same way humans are not guilty for killing animals*.

*It would still be a matter of guilt if the animal-slaughter was done contrary to other norms (such as the norms against animal abuse).

"are we attempting to find a bear or jaguar guilty for killing a human?" - but we do, there are plenty of news stories about a specific tiger, leopard, shark, or bear that is hunted and killed because it has killed humans. – Bent – 2019-02-19T10:29:50.940

I thought your argument was turning the premise on its head: The intrinsic property of humans is not a greater value but that we distinguish between good and evil; consequently murder is not forbidden because we are more valuable but because we realize it's evil. We realize that with respect to animals as well, just to a smaller degree, and it's also codified in many jurisdictions in the shape of animal protection laws, as you mention. – Peter - Reinstate Monica – 2019-02-19T12:46:21.240

@PeterA.Schneider, my argument (elsewhere) about how we are still cruel to "the octopus" is not that killing an octopus is wrong, but that our norms aren't a result of degrees of sentience. Our norms, from all that I can tell, are built on the value of an individual human life and the unvalue of an individual animal life. Here I'm arguing that we don't have any knowledge of animal norms, but we do have knowledge of human norms, and so therefore we won't know about an ontological / universal norm of killing but we do know about an ontological / universal norm of killing humans. – elliot svensson – 2019-02-19T15:06:49.710


Humans are, in a way, a special species. We ask questions that go far beyond the need to get by and survive which apparently suffices to animals and plants. For example, we ask: Why are we here? What is our purpose? By asking and analyzing we get insight into nature and end up being able to do what every animal can and more - albeit with the help of self-built devices.

That indicates we are both part of nature and apart from it, standing in a position to observe and analyze. That suggests we have a value higher than the rest of the world around us and the decision to consider it wrong to kill a human flows from that though not everybody makes that decision (at least not fundamentally.)

However, as we are also part of nature, we still have to understand and respect our role within it. Everything plays a role and has innate value just by the virtue of existing. Using our environment in harmony with the cosmic laws that define these roles is important, otherwise we create damage to the entire system.

Quoting religion (the Bible in this case): Humans are masters of creation, created in the image of the creator. That means our ability to observe, analyze and create is a divine aspect. So, in a way, killing a human is like killing the creator.

Still, while this sets us apart from nature, allowing us to transcend it, a part of us belongs to it and we need to understand how we are fitting into the entire context.

3I believe this is incorrect simply by virtue of the fact that atheists, who do not believe we are made in the image of any supernatural being, tend to hold the same views as religious folk in that human life is innately worth more (at least to them). Were the reason for this value the idea that humans are created in the image of a supernatural being, then atheists would, by and large, have no qualms with murder and would kill a person just as quickly as they would kill a flea. Clearly this is not the case. – forest – 2019-02-17T09:04:06.760

It's entirely possible that other animals ask themselves Why are we here? What is our purpose? – CactusCake – 2019-02-18T18:06:50.870


Why does human life have innate value over that of other animals? Why is it wrong to murder another human, but morally permissible to hunt or fish?

If I love myself, then I love all others as well. Other people, of course. But also animals, trees, flowers, planets, stars, and ultimately the whole universe.

Yet as a biological organism, my body uses energy and quickly becomes depleted of nutrients, which I must replace by consuming foods such as plants, fish, and animals. I don't enjoy killing them, so I am very careful not to be wasteful. I'd kill them as humanely as possible. I try to get by on just eggs and milk. I eat vegetarian dishes, often. And I even go so far as to apologize to them, and to express gratitude to them, for using them as food.

Furthermore, I wouldn't even consider cannibalism, or eating another human being. For me, that is strictly taboo. Why?

Well of course I already mentioned that I love people. But I also sincerely admitted to loving all creatures. That's why I don't believe in exploiting animals. I only kill and eat what I absolutely must have to maintain healthy life.

But I do eat animal meat, while I would starve myself to death before engaging in cannibalism (even if they had died of natural causes or accident). I would kill a game animal to eat, but would feel extreme guilt and shame over killing a human. The thought of eating human flesh is so revolting I wouldn't be able to get or keep it in my stomach. I might be forgiven for killing an animal for food, yet intentionally killing a human would be unforgivable.

So, what is the distinction between loving humans and loving [other] animals?

What is the distinction between the value of humans vs. the value of animals? And why is it innate?

The “depth” of love is to be explained in terms of a notion of identifying with one’s beloved, one might have a concern for one’s beloved that is analogous to one’s concern for oneself.

When I am hungry, before eating I evaluate my food by answering a few questions about its quality. The first question usually is, "What species?" Fortunately, I've never been offered human flesh for dinner, but I wouldn't eat it anyway, because I personally identify with the human species. Perhaps cannibals do not, at least not enough to inhibit them from doing so.

I'm astonished that no answer seems to directly address the core issue: Humans are sentient beings. This is what distinguishes us from (other) animals, and what makes us valuable in each other's eyes.

I'm aware that "sentience" is a fuzzy concept and that it is not entirely sufficient to explain the value we bestow in fellow humans even when their mental capacity is minimal (with few exceptions, like Peter Singer). But I believe it's the underlying criteria which lets us establish a hierarchy of values in the animate world. There is a pretty clear hierarchy we establish in animals: Big apes and dolphins are more valuable than earth worms, and if we ever made contact with sentient aliens they would be on the same level as humans on this virtual "value scale".

3Perhaps you are thinking of sapience. Many other animals are sentient, not just us, but we are the ones where sapience most applies. – forest – 2019-02-18T12:19:36.980

@forest I'm not a native speaker but Merriam-Webster gives as one meaning "conscious of sense impressions" and "aware". I mean it in that sense, being literally self-conscious. As I said, it is a fuzzy term, and there is some overlap with animals. To the degree that animals show sentience (perceive pain, are rudimentary self-conscsious) we grant them more rights, morally and also legally.

You're right. It's just your first paragraph made it seem more black and white, as if humans are exclusive in their sentience. – forest – 2019-02-18T12:46:16.580

I don't think it makes sense to describe the hierarchy on a universal scale when we have not yet explored the rest of the universe (or at least, we shouldn't be so presumptuous as to put our own species at the top). – CactusCake – 2019-02-18T18:16:32.137

@CactusCake True; god-like beings would probably be "valued" higher than us mere mortals, and any offense against them would be sacrilegious. – Peter - Reinstate Monica – 2019-02-18T19:53:53.417

I don't see that our value of other creatures falls in line with sentience in all cases... consider the octopus, which has been described as "very smart" and yet, is eaten not just raw but alive by people around the world. – elliot svensson – 2019-02-18T22:34:26.763

@elliotsvensson The realization that octopi are smart is relatively recent -- relative to the forming of collective opinion. But generally new information, e.g. about fish feeling pain, slowly makes its way through the minds of the collective and changes opinion and law. Paradoxically, that you are concerned about octopi puts your argument in peril ;-). – Peter - Reinstate Monica – 2019-02-18T22:40:04.830

My empathy for non-human creatures is only powerful in analogy to my empathy for vulnerable humans. I wouldn't eat the live octopus, but I would eat a dead octopus. – elliot svensson – 2019-02-18T22:45:51.587

The problem with this viewpoint is that given our history it seems extremely unlikely that aliens should they exist won't be far and beyond the level of humans on this scale. Thus I don't see what would stop them from eating humans with impunity. – eddi – 2019-02-19T05:18:55.030

@elliotsvensson Whether we eat dead people is entirely independent of the question at hand here: What value we bestow on living humans, in comparison to living animals. – Peter - Reinstate Monica – 2019-02-19T15:48:05.630

@PeterA.Schneider, I guess what I meant was, "I wouldn't eat a live octopus, but I would slaughter a live octopus." – elliot svensson – 2019-02-19T15:50:25.897
