The bigotry of theologians [is] a malady which seems almost incurable. - David Hume

When we run over libraries, persuaded of these principles, what havoc must we make? If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning concerning matter of fact and existence? No. Commit it then to the flames: For it can contain nothing but sophistry and illusion.

The science of man is the only solid foundation for the other sciences. [All the other sciences] have a relation, greater or lesser, to human nature. ‘Tis impossible to tell what changes and improvements we might make in these sciences were we thoroughly acquainted with the extent and force of human understanding, and could explain the nature of the ideas we employ, and of the operations we perform in our reason.

It is well known, that, in all questions submitted to the understanding, prejudice is destructive of sound judgment, and perverts all operations of the intellectual faculties: it is no less contrary to good taste; nor has it less influence to corrupt our sentiment of beauty. It belongs to good sense to check its influence in both cases.
