. To him, conditions were universal and comprised the real world. The visible ones are just particulars, a mimicry of the real things.&nbsp. He believed that people perceive reality differently from what it is. Plato believed that what people think is reality, is not, and is the opposite of the truth. Nonetheless, in this theory, Plato emphasized a form of recognition rather than cognition (Dancy 18).

Plato believed that, beyond this physical world, there existed a perfect and ideal world. Human beings’ physical world is characterized by different imperfections, unevenness, and impurities that have been copied from the perfect, ideal world beyond the physical world. This is the case because our physical planet apes the real forms of the ideal, ideal world in a disorderly manner. However, Plato thought that there exists a connection between our physical world and the realms of ways. From this relationship, the mortal beings understand conditions and the order of life (Dancy 34).

The theory of substance in Aristotle’s Categories categorized substances into two groups, the primary importance and the secondary meanings.&nbsp. Direct implications are absolute objects, distinguished from other things, including secondary substances and other predicable. Aristotle’s Categories bases on the explanation of the importance of substances so that a person hearing it for the first time can be in a position to understand the concept. Also, it presents implications as a primitive concept, which people have little knowledge about (Spellman 22).

The theory of substance by Aristotle was developed as a way of counteracting Plato’s theory of forms. Aristotle considered a sense to be complicated and integrated, whereby there are the raw matter and a compound of the substance. He also explained some traits of importance, which are essential, as they define it. First, he believed that imports do not allow for levels or degrees. This, therefore, implies that something cannot be too much of a substance or too little of a substance.
