This paper proposes to recover the topic of the philosophy of scientific method from its late nineteenth-century roots. The subject matter of scientific method sprouted from key inferential ingredients identified by Charles Peirce. In this paper, the historical path is traversed from the viewpoint of contemporary Cognitive Structural Realism (CSR). Peirce’s semiotic theory of methods and practices of scientific inquiry prefigured CSR’s reliance on embodied informational structures and experimentation upon forms of relations that model generic scientific domains. Three results are (...) shown to follow from this convocation: (i) a naturalization of Peirce’s interconnected abductive, deductive and inductive stages of the logic of science, here characterized de novo in terms of CSR. (ii) a perspective to scientific modeling that incorporates processes of abstraction and generalization as originated from Peirce’s logic of science, and (iii) diagrammatic reasoning as a pivotal method in analyzing scientific reasoning in experimental practices.

Building upon Brentano’s Psychology from an empirical standpoint. Routledge, London, [1874] Brentano 1995) reintroduction of the concept of intentionality to the contemporary philosophy, Tim Crane has famously presented the intentionality as the mark of the mental. Accordingly, the problem of “intentional existence” has resurfaced in Crane’s revival of the Brentanoian theme. Here, I revise Crane’s construal of Brentano’s notion of intentional inexistence and reinterpret it in terms of a moderate version of relationalism. My relationalist theory of intentionality is inspired by (...) what goes by the name of Noneliminativist Structural Realism in the contemporary philosophy of science. NSR allows for a robust realist interpretation of the role of scientific models. The underlying insight of the paper is that it is best to be realist about the structure of the intentionality, which is the common element of the diverse theories of intentional objects. The Outcome is Structural Realist theory of Intentionality. I argue that SRI is not liable to the notorious objection of the impossibility of relata-less relations. I conclude that SRI fulfils the goal of robust psychological realism more economically and straightforwardly than Crane’s application of the notion of models. (shrink)
