Inorder to seek truth, it is necessary once in the course of our life, to doubt,as far as possible, of. A Priori Knowledge of Matters of Fact Do animals acquire all their knowledge of matters of fact and real existence from sense perception and causal reasoning? He proposed there were two separate types of matter or stuff that can exist independent of each other. We can prove the existence of these objects because we can understand them with our intellect. Seated alone by the fire, he resolves to demolish former opinions and rebuild his knowledge on more certain grounds. If he nonetheless falls into error, does it reflect badly on God? He starts by defining everything he could possibly doubt. If so, how can this be reconciled with Hume's system? If not, what are we to make of this restatement of definition a?
