Man is the only living being who has a developed self-awareness and death-awareness.
Theodosius DobzhanskyNature's stern discipline enjoins mutual help at least as often as warfare. The fittest may also be the gentlest.
Theodosius DobzhanskyThe more we know, the better we realize that our knowledge is a little island in the midst of an ocean of ignorance.
Theodosius DobzhanskyThe business of proving evolution has reached a stage when it is futile for biologists to work merely to discover more and more evidence of evolution. Those who choose to believe that God created every biological species separately in the state we observe them, but made them in a way calculated to lead us to the conclusion that they are the products of an evolutionary development are obviously not open to argument. All that can be said is that their belief is an implicit blasphemy, for it imputes to God an appalling deviousness.
