Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical ratio. A slight acquaintance with numbers will show the immensity of the first power in comparison to the second. By that law of our nature which makes food necessary to the life of man, the effects of these two unequal powers must be kept equal. This implies a strong and constantly operating check on population from the difficulty of subsistence. This difficulty must fall somewhere and must necessarily be severely felt by a large portion of mankind.

The office of the moral law is that of a pedagogue, to protect and educate us in the use of freedom. At the end of this period of instruction, we are enfranchised from every servitude, even from the servitude of law, since Love made us one in spirit with the wisdom that is the source of Law.

The moral law of the universe is progress.

Nothing is impossible to the man that can will. Is that necessary? That shall be. This is the only law of success.

We should never create by law what can be accomplished by morality.

Because of the law of cessation, a man is "as he thinketh in his heart." Nothing can happen without its adequate cause.

What is good” I asked in a musing mood. Order, said the law court; Knowledge said the school; Truth, said the wise man; Pleasure, said the fool; Love, said the maiden; Beauty, said the sage. Fame, said the soldier; Equity, said the seer. Spoke my heart sadly: “The answer is not here.” then within my bosom softly this I heard: “Each heart holds the secret: Kindness is the word.”

"Waste not, want not," is the law of nature.

The rule of law is essentially a negative value. The law inevitably creates a great danger of arbitrary power - the rule of law is designed to minimize the danger created by the law itself. Similarly, the law may be unstable, obscure, retrospective, etc., and thus infringe people’s freedom and dignity. The rule of law is designed to prevent his danger as well. Thus the rule of law is a negative virtue in two senses: conformity to it does not cause good except through avoiding evil and the evil which is avoided is evil which could only have been caused by the law itself.

It is in the law of our humanity that man must know good through evil. No great principle ever triumphed but through much evil. No man ever progressed to greatness and goodness but through great mistakes.

When a law is proposed in the people’s assembly, what is asked of them is not precisely whether they approve of the proposition or reject it, but whether it is in conforming with the general will which is theirs; each by giving his vote gives his opinion on this question, and the counting of votes yields a declaration of the general will. When, therefore, the opinion contrary to my own prevails, this proves only that I have made a mistake, and that what I believed to be the general will was not so. If my particular opinion had prevailed against the general will, I should have done something other than what I had willed, and then I should not have been free. This presupposes, it is true, that all characteristics of the general will are still to be found in the majority; when these cease to be there, no matter what position men adopt, there is no longer any freedom.

I believe marriage to be the best and most important relation that can exist between two human beings. If it has not often been realized hitherto, that is chiefly because husband and wife have regarded themselves as each other’s policeman. If marriage is to achieve its possibilities, husbands and wives must learn to understand that whatever the law may say, in their private lives they must be free.

When we pray, we should feel the seriousness of speaking directly to the Almighty. The concept of seriousness should not be mistaken for sadness since sadness is a transgression. Seriousness should stem from the true joy of fulfilling a mitzvah [biblical law or good deed], the joy of having the merit to pray to the Almighty.

The best way to do good to ourselves, is to do it to others; the right way to gather, is to scatter. This is the law of benefits between men; the one ought to forget at once what he has given, and the other ought never forget what he has received.

Ambition is like hunger; it obeys no law but its appetite.

Socialists are filled with the enthusiasm of equality... Equality of possession or of rights and equality before the law are diametrically opposed to each other. The object of equality before the law is to make the state entirely neutral.

Custom is the law of fools.

Facts, when combined with ideas, constitute the greatest force in the world. They are greater than armaments, greater than finance, greater than science, business and law because they constitute the common denominator of all of them.

Among the natural rights of the Colonists are these: First, a right to life; Secondly, to liberty; Thirdly, to property; together with the right to support and defend them in the best manner they can. These are evident branches of, rather than deductions from, the duty of self-preservation, commonly called the first law of nature.

He never taught any law or practice contrary to the Written Law. Only after his death... many of his disciples introduced practices and doctrines altogether foreign to him, removing thereby the cornerstone of the Law while winning the multitudes.
