Wax Example:Wax is not available to the senses;What is the wax; the idea of it.I have to know what wax is intuitively.Like water, H20, when I think of these things, I think ofthem only in intellectual terms (e.g., red, a certain wavelength; water is H20).A body is a point (Cartesian geometry).However, we still don’t know if wax is available, butthere is, then we can know:Pure mathematical geometry.64
