This paper aims to follow Peirce's thinking before the birth of so called pragmatism. The origins of pragmatism are said to spring up from late 1870s' papers Fixation of belief and mainly How to make our ideas clear.
When studying Peirce's early texts, we can find that pragmatic ideas linking meaning with practice presumably originating in the late 1870s, are presented even in early 1860s' texts. This is most particularly the case of Peirce's Treatise on Metaphysics.
The main claim of the paper is that even though in Peirce's early texts, pragmatism is not explicitly named nor defined, the ideas presented in it are based on the same ground as in later so called pragmatist texts, although they are not as sophisticated as that later, for example in terminological anchoring, and that ideas resulting from Peirce's pragmatist texts on the one hand, and from his early texts on the other, more importantly, must be taken as the basics of whole Peircean philosophy, because they stand as a ground for his logic, semiotics, and metaphysics.
