The circumstances of the world are continually changing, and the opinions of men change also; and as government is for the living, and not for the dead, it is the living only that has any right in it. That which may be thought right and found convenient in one age, may be thought wrong and found inconvenient in another. In such cases, who is to decide, the living, or the dead?

It requires but a very small glance of thought to perceive, that although laws made in one generation often continue in force through succeeding generations, yet that they continue to derive their force from the consent of the living. A law not repealed continues in force, not because it cannot be repealed, but because it is not repealed; and the non repealing passes for consent.

The mere man of pleasure is miserable in old age, and the mere drudge in business is but little better, whereas, natural philosophy, mathematical and mechanical science, are a continual source of tranquil pleasure, and in spite of the gloomy dogmas of priests and of superstition, the study of these things is the true theology; it teaches man to know and admire the Creator, for the principles of science are in the creation, and are unchangeable and of divine origin.

A long habit of not thinking a thing wrong gives it a superficial appearance of being right.

Oppression is often the consequence, but seldom or never the means of riches.

There are two distinct classes of what are called thoughts: those that we produce in ourselves by reflection and the act of thinking and those that bolt into the mind of their own accord.

Great part of that order which reigns among mankind is not the effect of government. It has its origin in the principles of society and the natural constitution of man. It existed prior to government, and would exist if the formality of government was abolished. The mutual dependence and reciprocal interest which man has upon man, and all the parts of civilised community upon each other, create that great chain of connection which holds it together.
