Abstract

As part of his epistemology and in his criticism of Heraclitus’ theory of constant flux and the Sophists’ worldview, the philosopher Plato argues, in a way that is as solid as it is graphic, that change has two dimensions. On the one hand, renewal and movement towards the creation of a new and hitherto unheard-of category; and, on the other, partial permanency, which maintains links with the essence, with the innermost parts of what comprises the being, thus configuring it as an identifying and distinctive factor. According to Plato, this is how the idea of movement makes sense, in contrast with that of replacement, which has various consequences for practical life.
