Russell Kirk is one of the foremost conservative philosophers of the 20th Century. Here are his first 5 tenets. A second posting will include 6 thru 10.
The Essence of Conservatism by Russell Kirk
(1) Men and nations are governed by moral laws; and those laws have their origin in a wisdom that is more than human—in divine justice. At heart, political problems are moral and religious problems. The wise statesman tries to apprehend the moral law and govern his conduct accordingly. We have a moral debt to our ancestors, who bestowed upon us our civilization, and a moral obligation to the generations who will come after us. This debt is ordained of God. We have no right, therefore, to tamper impudently with human nature or with the delicate fabric of our civil social order.
(2) Variety and diversity are the characteristics of a high civilization. Uniformity and absolute equality are the death of all real vigor and freedom in existence. Conservatives resist with impartial strength the uniformity of a tyrant or an oligarchy, and the uniformity of what Tocqueville called “democratic despotism.”
(3) Justice means that every man and every woman have the right to what is their own—to the things best suited to their own nature, to the rewards of their ability and integrity, to their property and their personality. Civilized society requires that all men and women have equal rights before the law, but that equality should not extend to equality of condition: that is, society is a great partnership, in which all have equal rights—but not to equal things. The just society requires sound leadership, different rewards for different abilities, and a sense of respect and duty.
(4) Property and freedom are inseparably connected; economic leveling is not economic progress. Conservatives value property for its own sake, of course; but they value it even more because without it all men and women are at the mercy of an omnipotent government.
(5) Power is full of danger; therefore the good state is one in which power is checked and balanced, restricted by sound constitutions and customs. So far as possible, political power ought to be kept in the hands of private persons and local institutions. Centralization is ordinarily a sign of social decadence.
