So I believe in humanism but I often feel while there is a disconnect between the lofty ideals of humanism and how to achieve it. For example, I could have someone practicing an anti-humanistic philosophy and would not be able to convince him of the ideals of humanism on logical grounds (alone). Fortunately, I managed to find solace in Nichiren Buddhism which makes the claim one can disarm the negative motivations of a human being and help him become a value creating individual.
What are some other humanistic philosophies which attack this problem? And how do they aim to resolve it?
My question is which philosophies not only uphold and defend the European charter of human rights but also give an tenable path towards it?
