Political scientists almost everywhere have promoted the expansion of government power. They have functioned as the clergy of oppression.

To gauge the understanding and insight that metaphysics provides is to ask whether, in the final analysis, it helps us to cope with our world and harmonize our existence with nature, humanity, and ourselves, and leads to greater freedom and self-realization. Metaphysics is only the beginning. The end is human progress.

[During the 20th century] ... 170 million men, women, and children have been shot, beaten, tortured, knifed, burned, starved, frozen, crushed, or worked to death buried alive, drowned, hung, bombed, or killed in any other of the myriad ways governments have inflicted death on unarmed, helpless citizens and foreigners.

Power kills, absolute power kills absolutely.

We have a solution for war. It is to expand the sphere of liberty.

Nobody can be trusted with unlimited power. The more power a regime has, the more likely people will be killed. This is a major reason for promoting freedom.

Concentrated political power is the most dangerous thing on earth.
