Yesterday we were thinking to ourselves that space is to spacious as time is to (x). After pondering it for a good ten or twenty seconds, we concluded that there is no word for (x).
Timaeus? Plato already yoinked that one for unrelated purposes, although the dialogue does indeed touch on our theme. According to Prof. Wiki,
Timaeus begins with a distinction between the physical world and the eternal world. The physical one is the world which changes and perishes: therefore it is the object of opinion and unreasoned sensation. The eternal one never changes: therefore it is apprehended by reason….
The two worlds are conditioned by the different nature of their objects. Indeed, "a description of what is changeless, fixed and clearly intelligible will be changeless and fixed," while a description of what changes and is likely, will also change and be just likely. "As being is to becoming, so is truth to belief." Therefore, in a description of the physical world, one "should not look for anything more than a likely story."
Platonism is one of the permanent possibilities of philosophy (or philosophizing). It is a respectable approach, but like most philosophies, it gets some things right and many things wrong.
