Skepticism literally means a thoughtful inquiry, the looking at a problem in a disinterested spirit, the surveying of a question from many sides. In this sense it is the very essence of philosophy and science.

Philosophy, like science, consists of theories or insights arrived at as a result of systemic reflection or reasoning in regard to the data of experience. It involves, therefore, the analysis of experience and the synthesis of the results of analysis into a comprehensive or unitary conception. Philosophy seeks a totality and harmony of reasoned insight into the nature and meaning of all the principal aspects of reality.

The state is the nursing mother of human culture.
