Question Answered

Sufficient Reason (Palider-2019) is an attempt to answer the following question: What is sufficient reason? How should it be defined?

See Sufficient Reason for more details.


A Sufficient Reason is an agent's actual reason for accepting a theory. It is sufficient as it guarantees, by the Sufficient Reason theorem (Palider-2019), that an agent accept the theory for which there is a sufficient reason. A sufficient reason aims to separate the components by which an agent accepts a theory: into acceptance of the theory that serves as a reason, the acceptance of Implication (Palider-2019), the employment of a method, and the acceptance of Normative Inference (Palider-2019). A sufficient reason is to be contrasted with a Reason (Palider-2019) as it further involves the acceptance of the reason. Some questions surrounding acceptance without a sufficient reason remain to be explored (Theory Acceptance without Sufficient Reason).
