Abstract:
Determining the essence of any substance requires the construction
of its definition. It is necessary to find a generic concept to construct a definition,
and it includes the scope of the definition concept. However, there are
such concepts to be the most general of their kind, and therefore generic concepts
cannot be found for them. These concepts are meant to be three most
general philosophical categories: God, man, and the world. We call these three
categories as permanent metaphysical structures. Consequently, human always
seeks to outline the objects of his interest in his mind. If a definition is not
possible, then they are replaced by explications or quasi-definitions.
