Ideas are indeed the most dangerous weapons in the world. Our ideas of freedom are the most powerful political weapons man has ever forged.

The challenge to our liberties comes frequently not from those who consciously seek to destroy our system of government, but from men of goodwill - good men who allow their proper concerns to blind them to the fact that what they propose to accomplish involves an impairment of liberty.

Since when have we Americans been expected to bow submissively to authority and speak with awe and reverence to those who represent us?

When man ventures into the wilderness, climbs the ridges, and sleeps in the forest, he comes in close communion with his Creator. When man pits himself against the mountain, he taps inner springs of his strength. He comes to know himself.

The concept of the public welfare is broad and inclusive ... the values it represents are spiritual as well as physical, aesthetic as well as monetary. It is within the power of the legislature to determine that the community should be beautiful as well as healthy, spacious as well as clean, well balanced as well as carefully patroled.

What we must remember, however, is that preservation of liberties does not depend on motives. A suppression of liberty has the same effect whether the suppressor be a reformer or an outlaw. The only protection against misguided zeal is constant alertness to infractions of the guarantees of liberty contained in our Constitution. Each surrender of liberty to the demands of the moment makes easier another, larger surrender. . .
