Reality exists independent of human minds, but our understanding of it depends on the beliefs we hold at any given time.
Michael Shermer at Scientific American:
- We form our beliefs for a variety of subjective, emotional and psychological reasons in the context of environments created by family, friends, colleagues, culture and society at large.
- After forming our beliefs, we then defend, justify and rationalize them with a host of intellectual reasons, cogent arguments and rational explanations.
- Beliefs come first; explanations for beliefs follow.
According to Shermer, we reinforce bias.
