Question

what is main perpose of life
every one discuss then I will answer?

Answer 1

philosophy have provided an answer to the question of what, if anything, makes life meaningful, although they typically have not put it in these terms. Consider, for instance, Aristotle on the human function, Aquinas on the beatific vision, and Kant on the highest good. While these concepts have some bearing on happiness and morality, they are straightforwardly construed as accounts of which final ends a person ought to realize in order to have a life that matters. Despite the venerable pedigree, it is only in the last 50 years or so that something approaching a distinct field on the meaning of life has been established in Anglo-American philosophy, and it is only in the last 30 years that debate with real depth has appeared. Concomitant with the demise of positivism and of utilitarianism in the post-war era has been the rise of analytical enquiry into non-hedonistic conceptions of value, including conceptions of meaning in life, grounded on relatively uncontroversial (but not certain or universally shared) judgments of cases, often called “intuitions.” English-speaking philosophers can be expected to continue to find life's meaning of interest as they increasingly realize that it is a distinct topic that admits of rational enquiry to no less a degree than more familiar ethical categories such as well-being, virtuous character, and right action.
