It is old age, rather than death, that is to be contrasted with life. Old age is life's parody, whereas death transforms life into a destiny: in a way it preserves it by giving it the absolute dimension. Death does away with time.Simone de Beauvoir
The consciousness of the falsity of present pleasures, and the ignorance of the vanity of absent pleasures, cause inconstancy.Blaise Pascal
The only obligation which I have a right to assume is to do at any time what I think right.Henry David Thoreau
Philosophically, the universe has really never made things in ones. The Earth is special and everything else is different? No, we've got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, it's one of a hundred billion galaxies. And the universe - maybe it's countless other universes.Neil deGrasse Tyson
