Two Meanings of Platonic

The two most common senses of platonic come from the same source, yet are different enough in meaning that it is rather important to distinguish between them. The original sense relates to the ancient Greek philosopher, Plato, or to his philosophy. It will always be capitalized. A secondary meaning that also stems from the name of the philosopher describes something (such as feelings or a relationship) that is characterized by an absence of romance or sex (a platonic relationship in this sense might simply be called a friendship). This sense alludes to Plato’s belief that love between people could be so strong as to transcend physical attachments.
