A method of science is a term used by Charles S. Peirce to denote a specific method of inquiry (or way of achieving belief).
Unlike the methods of perseverance, authority, and the a priori method, the scientific method assumes that there are real events and objects with which our representations may or may not agree.
For Peirce, the hypothesis that something is real distinguishes science from other ways of establishing beliefs. For him, the reality is new, which may be different from what one or another’s researcher beliefs, but it is also what would be discovered indefinitely by the scientific community.
Thus defined, the reality is the possible other of what we think but is ultimately accessible to our understanding.
The assumption that such realities exist makes possible a form of research that is open to correction and self-correction.
