The main force used in the evolving world of humanity has hitherto been applied in the form of war.

Nowhere is Universalism welcomed and encouraged by a people; everywhere governments have forced and are forcing Universalism upon unwilling and resistant subjects.

Civilization, we shall find, like Universalism and Christianity, is anti evolutionary in its effects; it works against the laws and conditions which regulated the earlier stages of man's ascent.

No tempting form of error is without some latent charm derived from truth.

There are the further difficulties of building a population out of a diversity of races, each at a different stage of cultural evolution, some in need of restraint, many in need of protection; everywhere a bewildering Babel of tongues.

I prize the conditions under which I have lived because they have permitted me to choose my opportunities, to inquire into such matters as interested me, and to publish what I believed to be true, uncontrolled by any central authority.

My personal conviction is that science is concerned wholly with truth, not with ethics.
