Toleration is good for all, or it is good for none.

The greatest crimes do not arise from a want of feeling for others but from an over-sensibilit y for ourselves and an over-indulgence to our own desires

Religion is essentially the art and the theory of the remaking of man. Man is not a finished creation.

The science of constructing a commonwealth or renovating it, or reforming it, is...not to be taught a priori...That which in the first instance is prejudicial may be excellent in its remoter operation, and its excellence may rise even from the ill effects it produces in the beginning. The reverse also happens; and very plausible schemes, with very pleasing commencements, have often shameful and lamentable conclusions.

Nnothing tends more to the corruption of science than to suffer it to stagnate. These waters must be troubled, before they can exert their virtues.

The liberty I mean is social freedom. It is that state of things in which liberty is secured by the equality of restraint. A constitution of things in which the liberty of no one man, and no body of men, and no number of men, can find means to trespass on the liberty of any person, or any description of persons, in the society. This kind of liberty is, indeed, but another name for justice.

In a democracy the majority of citizens is capable of exercising the most cruel oppressions upon the minority...and that oppression of the majority will extend to far great number, and will be carried on with much greater fury, than can almost ever be apprehended from the dominion of a single sceptre. Under a cruel prince they have the plaudits of the people to animate their generous constancy under their sufferings; but those who are subjected to wrong under multitudes are deprived of all external consolation: they seem deserted by mankind, overpowered by a conspiracy of their whole species.
