Platonist Manifesto

Extract

Here is a short, rough statement of the Platonism I defend:

There exist things that are not the objects of any actual or possible sense-experience, and that are not themselves experiences of any sort. These things can only be grasped by the intellect: they can′t be seen, touched, tasted, heard or smelt but they can be known.

Further, these things are a main concern of philosophy.
