 But physical beauty is atypical being a Form that humans want to know. This is the second reason Plato makes beauty such a frequent example of a Form. The process known as anamnêsis or recollection is more plausible for beauty than it is for most other properties. The philosophical merit of equivocally F things is that they come bearing signs of their incompleteness, so that the inquisitive mind wants to know more (Republic 523c–524d). But not everyone can read those signs of incompleteness. Soft or large items inspire questions in minds of an abstract bent. The perception of examples of justice or self-control presupposes moral development before someone can recognize a law’s double nature as just and unjust. By contrast, beautiful things strike everyone, and arouse everyone’s curiosity. Therefore, beauty promises more effective reflection than any other property of things. Beauty alone is both a Form and a sensory experience (Phaedrus 250d).
