I would be satisfied with the life I have lived if I can honestly say that I possessed integrity. By integrity I mean that A.) I consistently acted so as to maximize the interests of all those who can be affected by my actions (favoring greater interests over lesser ones), not counting my own personal interests as any greater or lesser then those of any other sentient being and B.) that I only believed that which I had reason to believe based on a rigorous analysis of the evidence available to me. These two maxims are, to my way of thinking, the pre-requisites for living a rational, humanistic life, one which possesses a moral/intellectual unity.
