The heart of the liberal philosophy is a belief in the dignity of the individual, in his freedom to make the most of his capacities and opportunities according to his own lights, subject only to the proviso that he not interfere with the freedom of other individuals to do the same. This implies a belief in the equality of man in one sense; in their inequality in another.

The high tenet of this philosophy (Liberalism) is that Liberty is an endowment from the Creator of every individual man and woman upon which no power, whether economic or political, can encroach, and that not even the government may deny. And herein it challenges all other philosophies of society and government; for all others, both before and since, insist that the individual has no such unalienable rights, that he is but the servant of the state. Liberalism holds that man is master of the state, not the servant; that the sole purpose of government is to nurture and assure these liberties. All others insist that Liberty is not a God-given right; that the state is the master of the man.

In its origin, liberalism had no ambition to be universal either in the sense of claiming to be valid for everyone and every human society or in the sense of purporting to give an answer to all the important questions of human life. … The ideal of liberalism is a practically engaged political philosophy that is both epistemically and morally highly abstemious. That is, at best, a very difficult and possibly a completely hopeless project. It is therefore not surprising that liberals succumb again and again to the temptation to go beyond the limits they would ideally like to set for themselves and try to make of liberalism a complete philosophy of life. … In the middle of the twentieth century, Kantianism presented itself as a “philosophical foundation” for a version of liberalism, and liberals at that time were sufficiently weak and self-deceived (or strong and opportunistic) to accept the offer.

Liberalism is the philosophy for our time, because it does not try to conserve every tradition of the past, because it does not apply to new problems the old doctrinaire solutions, because it is prepared to experiment and innovate and because it knows that the past is less important than the future.

[L]iberalism is above all an attitude toward life and society based on tolerance and respect, a love for culture, a desire to coexist with others and a firm defense of freedom as a supreme value. A freedom that is, at the same time, the driving force of material progress, of science, arts, and letters, and of a civilization that has produced sovereign individuals, with their independence, their rights, and their responsibilities that are always held in balance with those of other individuals, protected by a legal system that guarantees coexistence within diversity. Economic freedom is a key element of liberal doctrine but certainly not the only one.

Now by Liberalism I mean false liberty of thought, or the exercise of thought upon matters, in which, from the constitution of the human mind, thought cannot be brought to any successful issue, and therefore is out of place. Among such matters are first principles of whatever kind; and of these the most sacred and momentous are especially to be reckoned the truths of Revelation. Liberalism then is the mistake of subjecting to human judgment those revealed doctrines which are in their nature beyond and independent of it, and of claiming to determine on intrinsic grounds the truth and value of propositions which rest for their reception simply on the external authority of the Divine Word.

"The fact is that libertarianism is not and does not pretend to be a complete moral or aesthetic theory; it is only a political theory, that is, the important subset of moral theory that deals with the proper role of violence in social life.

Political theory deals with what is proper or improper for government to do, and government is distinguished from every other group in society as being the institution of organized violence. Libertarianism holds that the only proper role of violence is to defend person and property against violence, that any use of violence that goes beyond such just defense is itself aggressive, unjust, and criminal. Libertarianism, therefore, is a theory which states that everyone should be free of violent invasion, should be free to do as he sees fit, except invade the person or property of another. What a person does with his or her life is vital and important, but is simply irrelevant to libertarianism.

It should not be surprising, therefore, that there are libertarians who are indeed hedonists and devotees of alternative lifestyles, and that there are also libertarians who are firm adherents of "bourgeois" conventional or religious morality. There are libertarian libertines and there are libertarians who cleave firmly to the disciplines of natural or religious law. There are other libertarians who have no moral theory at all apart from the imperative of non-violation of rights. That is because libertarianism per se has no general or personal moral theory.

Libertarianism does not offer a way of life; it offers liberty, so that each person is free to adopt and act upon his own values and moral principles. Libertarians agree with Lord Acton that "liberty is the highest political end" — not necessarily the highest end on everyone's personal scale of values."

The liberalism with which I am concerned is a version of liberalism prominent in the moral and legal and political philosophy of the day: a liberalism in which the notions of justice, fairness, and individual rights play a central role, and which is indebted to Kant for much of its philosophical foundation.

What do we mean by this Liberalism of which we talk? … I should say it means the acknowledgement in practical life of the truth that men are best governed who govern themselves; that the general sense of mankind, if left alone, will make for righteousness; that artificial privileges and restraints upon freedom, so far as they are not required in the interests of the community, are hurtful; and that the laws, while, of course, they cannot equalise conditions, can, at least, avoid aggravating inequalities, and ought to have for their object the securing to every man the best chance he can have of a good and useful life.

The second item in the liberal creed, after self-righteousness, is unaccountability. Liberals have invented whole college majors— psychology, sociology, women's studies— to prove that nothing is anybody's fault. No one is fond of taking responsibility for his actions, but consider how much you'd have to hate free will to come up with a political platform that advocates killing unborn babies but not convicted murderers. A callous pragmatist might favor abortion and capital punishment. A devout Christian would sanction neither. But it takes years of therapy to arrive at the liberal view.

[T]here is much in the liberalistic theory which is good and true; for example, not to say more, the precepts of justice, truthfulness, sobriety, self-command, benevolence, which, as I have already noted are among its avowed principles, and the natural laws of society. It is not till we find that this array of principles is intended to supersede, to block out, religion, that we pronounce it to be evil. There never was a device of the Enemy, so cleverly framed, and with such promise of success.

Liberalism should be found not striving to spread bureaucracy but striving to set bounds to it. True liberalism seeks all legitimate freedom first in the confident belief that without such freedom the pursuit of all other blessings and benefits is vain. That belief is the foundation of all American progress, political as well as economic.

The principle of liberalism is to have no fixed principle and to contend that this is in itself a principle.

The principal feature of American liberalism is sanctimoniousness. By loudly denouncing all bad things — war and hunger and date rape — liberals testify to their own terrific goodness. More important, they promote themselves to membership in a self-selecting elite of those who care deeply about such things.... It's a kind of natural aristocracy, and the wonderful thing about this aristocracy is that you don't have to be brave, smart, strong or even lucky to join it, you just have to be liberal.
