The physical structures of organisms play only a minor and secondary role... The only requirement which physical structure must fulfill is that it allow the characteristic behaviors themselves to be manifested. Indeed, if this were not so, it would be impossible to understand how a class of systems as utterly diverse in physical structure as that which comprises biological organisms could be recognised as a unity at all.

In contrast to the asexual chasteness of official communist art, Nazi art is both prurient and idealizing. A utopian aesthetics (physical perfection; identity as a biological given) implies an ideal eroticism: sexuality converted into the magnetism of leaders and the joy of followers. The fascist ideal is to transform sexual energy into a "spiritual" force, for the benefit of the community.
Susan Sontag
Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation for the existence and apparently purposeful form of all life, has no purpose in mind. It has no mind and no mind's eye. It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of watchmaker in nature, it is the blind watchmaker.
Richard Dawkins
Ignorance of each other is what has made unity impossible in the past. Therefore we need enlightenment. We need more light about each other. Light creates understanding, understanding creates love, love creates patience, and patience creates unity. Once we have more knowledge (light) about each other, we will stop condemning each other and a United front will be brought about.

Man is in pursuit of two goals: he is looking for happinesse and, being by essence empty ("étant vide par essence", Fr.), he is trying to fill (or take up, - "remplir", Fr.) his life; the latter reason play a more considerable role than we ordinarily think. What we take for vainglory, ambition, love of power and riches (or wealth), is often, indeed, a need to mask this emptiness, a need to let one's hair down (or to live it up), to put oneself on a false scent or trail.

It is now generally accepted that the roots of our ethics lie in patterns of behavior that evolved among our pre-human ancestors, the social mammals and that we retain within our biological nature elements of these evolved responses. We have learned considerably more about these responses, and we are beginning to to understand how they interact with our capacity to reason.
