Just what future the Designer of the universe has provided for the souls of men I do not know, I cannot prove. But I find that the whole order of Nature confirms my confidence that, if it is not like our noblest hopes and dreams, it will transcend them.

It is the nature of truth in general, as of some ores in particular, to be richest when most superficial.

Then not only custom, but also nature affirms that to do is more disgraceful than to suffer injustice, and that justice is equality.

Nature cannot be tricked or cheated. She will give up to you the object of your struggles only after you have paid her price.

The deepest principle in human nature is the craving to be appreciated.
