We have a right to know or may lawfully know any truth. And a right to know any truth whatsoever implies a right to think freely.

By freethinking I mean the use of the understanding in endeavoring to find out the meaning of any proposition whatsoever, in considering the nature of the evidence for or against, and in judging of it according to the seeming force or weakness of the evidence.

Apologys for self-evident Truths can never have any effect on those who have so little Sense as to deny them. They are the Foundation of all Reasoning, and the only just Bottom on which Men can proceed in convincing one another of the Truth: and by consequence whoever is capable of denying them, is not in a condition to be informed.

Willing or preferring is the same with respect to good and evil, that judging is with respect to truth or falsehood.

I am obliged to believe certain opinions myself. No man's belief will save me except my own.

It is not enough to render things equal to the will, that they are equal or alike in themselves.
