THE SUPREME PRINCIPLES OF BEING ARE THE FOLLOWING:

1. THE PRINCIPLE OF IDENTITY

2. THE PRINCIPLE OF NON-CONTRADICTION

3. THE PRINCIPLE OF EXCLUDED MIDDLE

4. THE PRINCIPLE OF CAUSALITY

5. THE PRINCIPLE OF SUFFICIENT REASON

Philosophy can serve as a principle of sufficient reason by seeking to provide explanations and reasons for various phenomena or beliefs. It can also adhere to the principle of non-contradiction by aiming to ensure that ideas and arguments are logically coherent and do not contain inherent contradictions. These principles help philosophy to maintain rigor and clarity in its methods of inquiry and analysis.

Aristotle argued that according to his principle of non-contradiction, something cannot both be and not be at the same time and in the same sense. In other words, he believed that contradictions cannot exist.

In his Republic, Plato explicitly states the principle of non-contradiction, i.e. something cannot both be A and not A at the same time in the same way, he may be the first thinker to ever explicitly define this central principle of reasoning in clear terms in writing.

The principle of contradiction states that two contradictory statements cannot both be true at the same time. It is a fundamental law of logic that helps to identify and resolve logical inconsistencies or fallacies in arguments. Adhering to this principle is essential in maintaining logical coherence and validity in critical thinking.
