Tolerance is held to be a condition of mind which is encouraged by, and is necessary for, civilization.

A drunkard is one thing, and a temperate man is quite another.

This world of ours has been constructed like a superbly written novel: we pursue the tale with avidity, hoping to discover the plot.

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

It is just because civilization is ever evolving, changing, and becoming more complicated, that experts find it so difficult to define it in explicit terms.

Religious leaders and men of science have the same ideals; they want to understand and explain the universe of which they are part; they both earnestly desire to solve, if a solution be ever possible, that great riddle: Why are we here?

I am a rank individualist.
