Abstract
Plato’s Theory of Forms is a response to Heraclitus’ philosophy that all things are in a state of becoming. Forms exist in an eternal and unchanging place not in reality. According to Heraclitus, changes are perceivable by the senses which are recognized by processes that occur in nature, such as the existence of fire. Thus, the central action of the mind is to develop ideas about the causes and effects of beliefs that transform opinion into knowledge. This method of reasoning that only focuses on the relations between real things and the mind begins with C.S. Peirce, the American pragmatist that claimed the concept of reality was derived from nothing external to the world. In order to describe some ways that thinking unfolds, it is necessary to create a boundary line between language and experience. This view of context provides the grounds for logic to evolve in metaphysics.
