Sociology is the mother of all social sciences justfy this statement and show how it is related to political science and politics?

Philosophy generally is seen as mother of all sciences.

I don't think that there is much philosophy behind current 'rational' science.

Or it must be the writings of the greatest fantast of all times Immanuel Kant.

Sociology with its belief in 'rational' procedures is more like a fundamental religion.

Of course all of science is religion, but technological science gives useful tools to research reality. Studying languages, of geography, geology, and so on, also gives us useful tools.

Sociology was not there (in present shape) before psychiatry or philosophy, and that seems to me a condition for being mother.

I'm sorry but the Social Sciences never reached a level of being useful like technology. Instead it gave us hundreds of prejudices, a strong belief in individualism, and a tolerant attitude towards capitalism.

Where did that bring us?
