همه‌چیز را بسنج؛ همواره باورهای خود را با واقعیات باز آزما، و آماده‌باش تا حتی عزیزترین باورهایت را هم که با واقعیت نمی‌خوانند کنار نهی. عقاید خود را… - Richard Dawkins

Each generation is a filter, a sieve; good genes tend to fall through the sieve into the next generation; bad genes tend to end up in bodies that die young or without reproducing.

Living organisms had existed on earth, without ever knowing why, for over three thousand million years before the truth finally dawned on one of them. His name was Charles Darwin. To be fair, others had had inklings of the truth, but it was Darwin who first put together a coherent and tenable account of why we exist.

Let us try to teach generosity and altruism, because we are born selfish. Let us understand what our own selfish genes are up to, because we may then at least have the chance to upset their designs, something that no other species has ever aspired to do.
