So far I have been speaking of theoretical science, which is an attempt to understand the world. Practical science, which is an attempt to change the world, has been important from the first, and has continually increased in importance, until it has almost ousted theoretical science from men's thoughts.

Men fear thought as they fear nothing else on earth - more than ruin, more even than death.

I believe that when I die I shall rot, and nothing of my ego will survive.

When white men first effect contact with some unspoilt race of savages, they offer them all kinds of benefits, from the light of the gospel to pumpkin pie. These, however, much as we may regret it, most savages receive with indifference. What they really value among the gifts that we bring to them is intoxicating liquor which enables them, for the first time in their lives, to have the illusion for a few brief moments that it is better to be alive than dead.

In spite of Death, the mark and seal of the parental control, Man is yet free, during his brief years, to examine, to criticise, to know, and in imagination to create. To him alone, in the world with which he is acquainted, this freedom belongs; and in this lies his superiority to the resistless forces that control his outward life.

The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts.

It is only in marriage with the world that our ideals can bear fruit; divorced from it, they remain barren.
