In the following text I reexamine the connotations of the term habit from the perspective of Peirce’s pragmatism. I start by tracing back the roots of the term in the Metaphysical Club’s discussions of Alexander Bain’s theory of belief. By stressing the relative overlap between belief and habit I am also proposing that the latter term transcends the boundaries of empirical psychology. Peirce’s well-known antipathy to psychologism in logic raised the status of habit to a universal concept that participates in (...) the unlimited process of interpretation. Habit, therefore, falls into a new lineage of meaning that can be traced back to antiquity and turns into a generative notion with extensive connotations. As a result it becomes an inseparable part of Peirce architectonic philosophy, capable to shed new light on his evolutionary cosmology and metaphysics. Conceiving of habit as an operative element in the evolution of all phenomena in the universe is the main objective of this article. (shrink)
