"Many things, for aught I know, may exist, whereof neither I nor any other man hath or can have any idea or notion whatsoever"
About this Quote
The key move is the double lock: neither “I” nor “any other man” can have “any idea or notion whatsoever.” Berkeley’s empiricism treats ideas as the currency of meaning. If you can’t even mint the coin, you can’t pay for the claim. The line doesn’t merely concede mystery; it polices the border between humility and nonsense. It anticipates a modern irritation with armchair metaphysics: if a supposed object is definitionally unthinkable, what exactly are you doing when you assert it exists?
Context matters. Early 18th-century philosophy is wrestling with Locke’s distinction between primary qualities (supposedly in objects) and secondary qualities (in the mind), and with the broader anxiety that “material substance” is a placeholder term masquerading as an explanation. Berkeley’s subtext is combative: skeptics and materialists alike keep smuggling in concepts they cannot cash out experientially. By granting that there may be more than we can conceive, he avoids sounding like a dogmatic idealist while tightening the net around what we’re allowed to call knowledge.
