Transcendental Knowledge?

[Neo-Scholastic]

...something "apart from the senses" invokes something wholly not in experience, and "inexperiencable".

As for me "apart from the senses" applies the Aristotelian concept that forms and propositions do exist and are real, not in their own realm, but immanently across multiple manifestations. They are immaterial in the sense that they do not depend on any particular material to instantiate, i.e. a wooden triangle and a pencil sketch of three joined and straight lines, both partake of the form of triangularity. Likewise, there is a common meaning to "I am." and "Je le suis" even though the form of the proposition is entirely different. In both cases you do not directly perceive the forms or propositions as objects of sense; but rather the objects of sense allow you to know the existence of the forms and propositions.
