In fact, the basic axiom of empiricism, namely that truth can only be attained by means of verification or falsification by scientific investigation, itself cannot be verified. Thus, empiricism is founded on a fallacious starting point. Sensation might inform us that doors have two sides, but it cannot teach us that all doors must have two sides. No experience can disprove the idea that some doors might have one side. The universal proposition defining door can never be substantiated by sensory perception.
Empiricism is restricted to particular things.
Sixth, empiricism cannot tell us how the senses alone give us conceptions. Whereas rationalism, with its universal ideas, gives us an explanation for categories and similarities, empiricism does not. Seventh, solipsism is inescapable in an empiricist epistemology. No one else can experience them. These ideas can never be found in any experience.
