Of course, there is no reconciliation between the theory of evolution by natural selection and the traditional religious view of the origin of the human mind.

One difference between ants and humans is that while ants send their old women off to war, humans send their young men.

The growth of a naturalist is like the growth of a musician or athlete: excellence for the talented, lifelong enjoyment for the rest, benefit for humanity.

Not all ants use violence to dominate their world, some use more subtle methods.

Progress, then, is a property of the evolution of life as a whole by almost any conceivable intuitive standard.... let us not pretend to deny in our philosophy what we know in our hearts to be true.

Sometimes a concept is baffling not because it is profound but because it is wrong.
