Smells are the fallen angels of the senses.

What is worse than having no sight is being able to see but having no vision.

Now I feel as if I should succeed in doing something in mathematics, although I cannot see why it is so very important. . . The knowledge doesn't make life any sweeter or happier, does it?

The foundation of society is laid upon a basis of . . . individualism, conquest and exploitation . . . A social order such as this, built upon such wrong and basic principles, is bound to retard the development of all. The output of a cotton mill or a coal mine is considered of greater importance than the production of healthy, happy-hearted and free human beings. We, the people, are not free. Our democracy is but a name.

We cannot freely and wisely choose the right way for ourselves unless we know both good and evil.
