Difference between Locke’s Primary and Secondary Qualities?

The primary qualities of objects produce ideas in our minds that “resemble” the corresponding qualities in the objects that caused us to have those ideas. The secondary qualities of objects produce ideas in our minds that do not resemble the corresponding qualities in the objects that produced those ideas in our minds.

Where does Locke discuss primary and secondary qualities?

They do not exist in the external object. But look explains it as the primary qualities have powers which creates in our minds the secondary qualities we perceive.
