The Material and the Medial LOGIC
Some sources relate it with reason others with principles inherent in the function or expression of reality and its many aspects.
For example:
1. reasoning conducted or assessed according to strict principles of validity.
2. a formal scientific method of examining or thinking about ideas.
3. the formal principles of a branch of knowledge.
4. a method of reasoning that involves a series of statements, each of which must be true if the statement before it is true.
5. any particular formal system in which are defined axioms and rules of inference.
6. the system and principles of reasoning used in a specific field of study.
There are many other definitions given but the fundamental meaning remains the same.
Thus logic refers to a system or method which governs our understanding. This means that the premise must lead automatically or naturally to the conclusion.
For me, logic is realised from the laws or principles governing phenomena, which means that, the conclusions drawn must be explicit in the way we understand and relate to phenomena and consequently how we interact with reality. I believe that is how the three laws of logic came to be.
They are:
1. The Law of Identity.
Everything that exists has a specific nature. Each entity exists as something in particular and it has characteristics that are a part of what it is.
Identity is the concept that refers to all aspects of existence, that is, the aspect of existing as something in particular, with specific characteristics. An entity without an identity cannot exist because it would be nothing. To exist is to exist as something, and that means to exist with a particular identity.
The concept of identity is important because it makes explicit that reality has a definite nature. Since reality has an identity, it is knowable.
The proof of this is the experience of phenomena. That is, we only experience what is affirmed as an identity through its specific characteristics.
2. The Law of Non-Contradiction
First, a contradiction arises when two ideas each make the other impossible. Contradictions don't exist in reality because reality simply is as it is and does not contradict itself.
Only our ideas and interpretations can be contradictory.
It states that contradictory identities, circumstances or statements cannot both be true when having similar values. It is complementary to the law of identity.
3. The Law of Excluded Middle
It states that a proposition is either true or false. There is no middle ground between the two which is neither true nor false or both true and false. It is also complementary to the law of identity and the law of non-contradiction.
IS LOGIC SUBJECTIVE?
The claim that logic is subjective can take the form of:
1. a mere assertion, in which case, there are no grounds for believing it
2. an argument, in which case, it becomes the very thing it attempts to disprove and hence fails.
Logic is established or realised from the laws which govern the domain of knowledge (of phemomena or the reality they exist in) and in which both the subjective and the objective are aspects.
Therefore, as is readily apparent from the above argument, there is no excuse or escape from adhering to logic. There is no hiding behind the idea of subjectivity, circularity, paradoxes, etc. There are no assumed or unfounded premises or conclusions in the representation of logic. Everything is stated as it is related to in our experiences of reality. And that is the absolute validity of logic.
