Abstract

The question of how we come to accept new theories is a central area of inquiry in scientonomic discourse. However, there has yet to be a formal discussion of the subjective reasons an agent may have for accepting theories. This paper explores these epistemic reasons and constructs a historically sensitive definition of reason. This formulation takes an abstractionist stance towards the ontology of reasons and makes use of a composite basing relation. The descriptive and normative components of reasons are fully formulated in scientonomic terms through the application of the newly introduced notion of implication, and its separation from the notion of inference. In addition, the paper provides scientonomic definitions for sufficient reason, support, and normative inference. The fruitfulness of this formulation of reasons is illustrated by a few examples.
