There are no shortcuts in evolution.

The logic of words should yield to the logic of realities.

The greatest dangers to liberty lurk in the insidious encroachment by men of zeal, well meaning but without understanding.

Those who won our independence... valued liberty as an end and as a means. They believed liberty to be the secret of happiness and courage to be the secret of liberty.

Neutrality is at times a graver sin than belligerence.

Men long for an afterlife in which there apparently is nothing to do but delight in heaven's wonders.

Our government... teaches the whole people by its example. If the government becomes the lawbreaker, it breeds contempt for law; it invites every man to become a law unto himself; it invites anarchy.

The world presents enough problems if you believe it to be a world of law and order; do not add to them by believing it to be a world of miracles.

If we would guide by the light of reason we must let our minds be bold.

America has believed that in differentiation, not in uniformity, lies the path of progress. It acted on this belief; it has advanced human happiness, and it has prospered.

We are not won by arguments that we can analyze, but by tone and temper; by the manner, which is the man himself.

Most of the things worth doing in the world had been declared impossible before they were done.

There are no shortcuts in evolution.

If you would only recognize that life is hard, things would be so much easier for you.

The most important political office is that of the private citizen.

Fear of serious injury alone cannot justify oppression of free speech and assembly. Men feared witches and burnt women. It is the function of speech to free men from the bondage of irrational fears.

Publicity is justly commended as a remedy for social and industrial diseases. Sunlight is said to be the best of disinfectants; electric light the most efficient policeman.

Organisation can never be a substitute for initiative and for judgement.

We can have democracy in this country, or we can have great wealth concentrated in the hands of a few, but we can't have both.

In the frank expression of conflicting opinions lies the greatest promise of wisdom in governmental action.

If we desire respect for the law, we must first make the law respectable.

I abhor averages. I like the individual case. A man may have six meals one day and none the next, making an average of three meals per day, but that is not a good way to live.

Experience teaches us to be most on our guard to protect liberty when the government's purposes are beneficent.

To declare that in the administration of criminal law the end justifies the means to declare that the Government may commit crimes in order to secure conviction of a private criminal would bring terrible retribution.

A man is a better citizen of the United States for being also a loyal citizen of his state and of his city; for being loyal to his family and to his profession or trade; for being loyal to his college or his lodge.

Democracy rests upon two pillars: one, the principle that all men are equally entitled to life, liberty and the pursuit of happiness; and the other, the conviction that such equal opportunity will most advance civilization.

During most of my life, my contact with Jews and Judaism was slight. I gave little thought to their problems, save in asking myself, from time to time, whether we were showing by our lives due appreciation of the opportunities which this hospitable country affords. My approach to Zionism was through Americanism.

However great his outward conformity, the immigrant is not Americanized unless his interests and affections have become deeply rooted here. And we properly demand of the immigrant even more than this. He must be brought into complete harmony with our ideals and aspirations and cooperate with us for their attainment.

Let no American imagine that Zionism is inconsistent with patriotism. Multiple loyalties are objectionable only if they are inconsistent.

The difference between a nation and a nationality is clear, but it is not always observed. Likeness between members is the essence of nationality, but the members of a nation may be very different. A nation may be composed of many nationalities, as some of the most successful nations are.

What are the American ideals? They are the development of the individual for his own and the common good; the development of the individual through liberty; and the attainment of the common good through democracy and social justice.

What is Americanization? It manifests itself, in a superficial way, when the immigrant adopts the clothes, the manners and the customs generally prevailing here. Far more important is the manifestation presented when he substitutes for his mother tongue the English language as the common medium of speech.

There is a spark of idealism within every individual which can be fanned into flame and bring forth extraordinary results.

History is not life, but since only life makes history, the union of the two is obvious.

Organization can never be a substitute for initiative and for judgment.

Ownership has been separated from control; and this separation has removed many of the checks which formerly operated to curb the misuse of wealth and power.

Behind every argument lies someone's ignorance.

The best of wages will not compensate for excessively long working hours which undermine heath.

There is a spark of idealism within every individual which can be fanned into flame and bring forth extraordinary results.

Learn about the world, the way it works, any kind of science and anthropology, it's really an interesting place we live in. Evolution is a really fantastic idea, even more than the idea of God I think.

Sexual self-restraint is only a preliminary stage in the ego's evolution.

I believe that history might be, and ought to be, taught in a new fashion so as to make the meaning of it as a process of evolution intelligible to the young.

The theory of evolution is totally inadequate to explain the origin and manifestation of the inorganic world.

Why is it so painful to watch a person sink? Because there is something unnatural in it, for nature demands personal progress, evolution, and every backward step means wasted energy.

I believe in evolution. But I also believe, when I hike the Grand Canyon and see it at sunset, that the hand of God is there also.

Unless one is a religious fundamentalist and believes that man was created in the image and likeness of God, it is foolish to believe that human beings are exempt from biological classification and the laws of evolution that apply to all other life forms.

You have to look at history as an evolution of society.

If we turn to palaeontology to tell us about our biological evolution it is to prehistory that we look for evidence of the evolution of specifically human patterns of behaviour.

In formal logic, a contradiction is the signal of defeat, but in the evolution of real knowledge it marks the first step in progress toward a victory.
