Chance governs all. In a world of opinions, how do you decide which one to listen to first? Ultimately you still rely on your own senses to decide whose opinion on what is relevant is relevant.
According to Neil Postman, words of mouth or gossips are most relevant; next to that are printed words; last of all is TV news because the far-away events it reports have virtually no impact on your day-to-day life. How many people were inconvenienced by the 9.11 attack, even though most would admit it was a major event in their lives?
Nevertheless, regarding printed words, a Russellian would prescribe adventure during one's soldier period before everything else. The reason behind this is that words have no meanings before experience. In order to make sense of words, one has to have some experiences first. Take a perfectly good word such as "pineapple" for example, it is basically destitute of meanings to you unless you have smelled, touched and tasted one.
Every one has his soldier period during which he is brave and adventurous. If a person spends a good portion of his youth on gaining life experiences, chances are he will judge well later in life. On the other hand, if a person spends his youth in an ivory tower where he thinks he is learning words of wisdom when he is supposed to be smelling roses, braving thunders, flying high, diving deep, making friends and fending off adversaries, by the time he comes to the age of "full of wise saws and modern instances," he is mostly likely to be full of s***t.
Again, this is the view of a Russellian who believes that sensations are more fundamental than "abstract ideas," not the other way around.
