The bulk of the world's knowledge is an imaginary construction.

The few own the many because they possess the means of livelihood of all ... The country is governed for the richest, for the corporations, the bankers, the land speculators, and for the exploiters of labor. The majority of mankind are working people.

The majority of mankind is ground down by industrial oppression in order that the small remnant may live in ease.

A man can't make a place for himself in the sun if he keeps taking refuge under the family tree.

The saddest thing in life is people with sight, but without vision.

We should respect all people.
