schools of thought

1. The contemporary school of thought that has been gaining popularity is that of scientific and that such knowledge can only come from positive affirmation of theories through strict scientific method. Hence no knowledge is genuine unless it is based on generally observable facts. It is very acutely concerned with 'know-how' it does not account or explain for purpose and meaning as in why are things the way they are.
Well they are because they are and you can see them.
If you can't see it, they don't exist.

2. The general idea of relativism, that is there are no absolutes. The truth is dependent on you and your environment. So the truth is related to the existing culture environment or majority or generally accepted ideas. There are no standards here, no norms, everything is relative. The idea is that truth has many forms and this is one such form, or rather an amalgamation of co-existence.
The entire theory is flippant, in free flowing form, no strict codes and statutes, the outgrowth of this is the live and let live idea on life.

3. The essence of human life viz; culture, society, language, religion, philosophy, etc are nothing but necessary implements to support the life of mankind where he is in the annals of time. This is just a super structure erected to promote ones interest and convenience such that the believers would form a common point and create support structure to carry on their interest through priests and oracles in a way each supporting the other.

4. In contrast one might think, that these manifestations are nothing but ideas and notions of the subconscious mind mainly explained by Freudian theories of unfulfilled incest wishes during childhood and adolescence.

5. The last and oldest thought is that of creation. The fact of creation and thus a purpose and that we people are travelers on earth to tend and keep what the Good Lord has provided. The end of life being of restoration and the journey of now being of fulfilling our destiny. A one to one relationship between God and man, and the man to men relationship based on the one to one.

Needles to say, the last system of though is increasingly ignored and we tend to qualify our life with the other four.
The distinction in these schools of thought is that, the first #4 schools of thought are a general reaction in the subjects environment that shapes the subjects thought. The #5 school of thought is one where the subject chooses his/her thoughts and aligns it to his/her individual purpose to be fulfilled in conjunction to the environment.

The first #4 schools of thought allows one to infer that we are a product/end of the environment.
The last #5 schools of thought allows one to infer that we are a constituent that will yield an end.
