As I pointed out, all knowledge **originates **
in mental activity - not material objects! In that sense it is subjective. Introspection is knowledge that is both subjective and objective. It is unique because we are
directly aware of what occurs in our mind.
Our sensory and intellectual powers are principles of knowledge for without these powers we can have no knowledge but the cause of our knowledge is the external material world. We can have no knowledge of anything whatsoever without the sense impressions received through our five external senses from material objects. From these sense impressions the internal senses divide and unite and produce perceptions, images and recollections which produces a phantasm which is the final product of the senses and this phantasm is presented to the intellect. The intellect abstacts the forms of things from the sense phantasm and from their individuating matter and thus is able to perceive the nature and essences of material substances. We are not born with innate ideas. We get all our ideas from our contact with reality which contact is first made with our five external senses which is why as I said in a previous post that Aristotle said that the principle of knowledge is in the senses.
Our sensory and intellectual powers are passive powers, i.e., they are in potency. They are reduced from potency to act by the soul’s contact with the exteral material world which as I have said is first made with our five external senses.
The intellect itself in this life does not understand anything without a phantasm which is a sense image of some sort produced from the internal senses which get their data from the five external senses which in turn are the sense impressions of the material world.
In one sense, our knowledge is subjective because the knowledge of anything exists in the knower. In another sense, all true knowledge is objective because we gather all our knowledge from our contact with the material world.
