can you tell whether the complex idea of substance is made in mind to support other ideas or Locke is saying that it is outside in space?

@@sudhanshusaini504 simple ideas are combined by mind to create complex idea of substance(substratum in which qualities inhers), which(that substratum)we cannot verify empirically. So yes, complex ideas are created by mind from simple ideas.

@@sudhanshusaini504 complex ideas to support other ideas? What do you mean by this?

@@someshpawar6238 I meant whether that complex idea which mind has inferred is within the mind or mind has inferred it outside the mind I.e. basically referring to the object from which sensations came?

@@sudhanshusaini504 You already answered the question, as mind is inferring it, it(complex idea) must be in MIND(also mind create complex idea combining simple ideas so, it must be in mind i.e. complex idea). Let me elaborate, Locke cannot experience the object existing in outside world as he is an empiricist. But, he still accepts the existence of that object due to compulsion of thought(for example. Apple , he cannot experience but still accepts the existence of it)(this is where is he becomes inconsistent as an empiricist). And the complex idea exist in mind is the combination of qualities, copy of the object/substratum existing(as per locke as he assumes the outer space/world) in outside world (Representative theory).

Outside in space
