For both excessive and insufficient exercise destroy one's strength, and both eating and drinking too much or too little destroy health, whereas the right quantity produces, increases and preserves it. So it is the same with temperance, courage and the other virtues. This much then, is clear: in all our conduct it is the mean that is to be commended.
Beliefs have the power to create and the power to destroy. Human beings have the awesome ability to take any experience of their lives and create a meaning that disempowers them or one that can literally save their lives.
The history of liberty is the history of the limitation of governmental power, not the increase of it. When we resist . . . concentration of power we are resisting the powers of death, because concentration of power is what always precedes the destruction of human liberties.
