The great end of all human industry, is the attainment of happiness.…

A wise man's kingdom is his own breast: or, if he ever looks farther, it will only be to the judgment of a select few, who are free from prejudices, and capable of examining his work.

The life of man is of no greater importance to the universe than that of an oyster.

The sense of justice and injustice is not deriv'd from nature, but arises artificially... from education, and human conventions.

The same good sense, that directs men in the ordinary occurrences of life, is not hearkened to in religious matters, which are supposed to be placed altogether above the cognizance of human reason.

Does a man of sense run after every silly tale of hobgoblins or fairies, and canvass particularly the evidence? I never knew anyone, that examined and deliberated about nonsense who did not believe it before the end of his enquiries.

As to the Approbation or Esteem of those Blockheads who call themselves the Public, & whom a Bookseller, a Lord, a Priest, or a Party can guide, I do most heartily despise it.
