A Treatise of Human Nature

David Hume's A Treatise of Human Nature begins from dissatisfaction with the condition of philosophy. Celebrated systems often depend on principles accepted without proof, weak deductions, and parts that do not cohere. Disagreement persists from trivial questions to the most important matters, yet confidence and eloquence can win followers even when evidence is poor.

Hume does not treat this failure as a reason to abandon difficult reasoning. Popular suspicion of metaphysics may follow repeated disappointment, but truth about the mind cannot be reached without sustained attention. Easy answers would themselves be grounds for doubt when earlier thinkers have struggled with the same problems.

The proposed remedy is a science of human nature. Mathematics, natural philosophy, religion, morals, and other fields are all judged through human powers and faculties, so understanding the mind can clarify the foundations on which every science depends. The Treatise therefore shifts inquiry toward the processes by which people perceive, reason, feel, and evaluate. Its central ambition is methodological: replace unsupported systems with close examination of experience and build broader conclusions only from principles that an account of human nature can justify.
