Humanism is a way of life based on the application of scientific skepticism and free inquiry - rather than religion - to the resolution of human problems. It is inspired by natural beauty and human artistic expression. It is guided by the ethical principles of personal integrity, responsibility, and compassion, and the social principles of liberty, equality, minority rights, justice under law, and environmental responsibility. Humanism recognizes that our values come from our human nature, our various cultures, and our personal experiences, rather than divine revelation.
Humanists think for themselves as individuals. There is no area of thought we are unwilling to explore, question, or doubt. We feel free to inquire and then agree or disagree with any given claim.
Humanists use reason and logic as tools in understanding the universe we live in. We find that when reason is abandoned, there is no "court of appeal" where differences in opinion can be settled. Therefore, reason, when applied to the evidence of our senses and accumulated knowledge, is the most reliable guide in making our daily choices and decisions.
Humanists base their understanding of the world on what they can perceive with their senses and what they can comprehend with their minds. They reject transcendental or supernatural concepts as there is no rational way to test their truth and validity. They hold the scientific method as the most appropriate way to test the validity of ideas. (from the HSNM website)
