Science has gone a long way toward helping man to free himself from the burden of hard labor; yet, science itself is not a liberator. It creates means, not goals. It is up to men to utilize those means to achieve reasonable goals.
I have always thought that all men should be free; but if any should be slaves, it should be first those who desire for themselves, and secondly those who desire it for others. Whenever I hear anyone arguing for slavery, I feel a strong impulse to see it tried on him personally.
Probability but no truth, facility but no freedom--it is owing to these two fruits that the tree of knowledge cannot be confused with the tree of life.
Pharisaism, obtuseness and tyranny reign not only in the homes of merchants and in jails; I see it in science, in literature, and among youth. I consider any emblem or label a prejudice.... My holy of holies is the human body, health, intellect, talent, inspiration, love and the most absolute of freedoms, the freedom from force and falsity in whatever forms they might appear.
