Plato’s theory, expressed as a chart, separates reality and knowledge, with five aspects pertaining to each. Human life is confined to the bottom two on each side – a sensible object, how we perceive the sensible object, the idea of the object, and a human’s imagined version of the object. Above the human realm, we can reason through discussion what constitutes a form, or the perfect version of the object. A lower form is the perfect version of a specific object, while the higher form, which can only be determined through truth, is more broad in scope.
