The secondary literature on Peirce was scant until after [[World War II]].  Much of his huge output is still unpublished.  An innovator in fields such as logic, mathematics, [[philosophy of science]], research methodology, [[semiotics]], [[epistemology]], and [[metaphysics]], he considered himself a logician first and foremost.  While he made major contributions to the development of formal logic as it is known today, ''logic'' for him encompassed much of what is now studied under the philosophies of knowledge, language, and science.  Peirce saw logic as the formal branch of the theory of signs, or ''[[semiotics]]'', here using ''formal'' in the sense of ''[[normative]]'' or what he called ''quasi-necessary''.  In 1886, he saw that logical operations could be carried out by electrical switching circuits, an idea used decades later in the development of [[electronic computer]]s.
