The research is a comparative study of the atomic theories of Kanada and Democritus. Because of their pluralistic tendencies, emphasis on causality, their materialistic account of sense knowledge, and their attempt to explain the physical system by means of reduction to the configuration of its constitutive elements, both philosophers present an epistemological base that could accommodate scientific inquiry. Notwithstanding the early and expansive beginning of Indian atomism, modern scientific atomic theory traces its origin to Democritus. Through cross-cultural critical engagement of (...) parallel ideas between Kanada and Democritus, the paper aims to discover the common problems that they dealt with in order to further our understanding of the early history of atomic theory, to evaluate the relative merits and limitations of their proposed solutions, to resolve some difficulties that each account faces by appealing to the other, and to highlight their contributions to the emergence of atomic worldview.

I argue that Democritus presents a theory of colour in which the predominance of atomic shapes and microstructural arrangements are neces- sary but not sufficient for colour vision. Focusing primarily on Democritus’ basic colours, I analyse his microstructural account, providing a new analysis of the natural and technological underpinnings of his method of explanation. I argue that the notion of predominance allows Democritus to account for both the varia- tion and the repeatable correspondence of colour perception by setting limits on (...) possible microstructures. This account, however, is complicated by the evidence for a Democritean theory of colour transformation and distorted vision, which arise from a dynamic interplay of features at the level of microstructures and at the level of perception.

Many philosophers have claimed that there is a tension between the impenetrability of matter and the possibility of contact between continuous bodies. This tension has led some to claim that impenetrable continuous bodies could not ever be in contact, and it has led others to posit certain structural features to continuous bodies that they believe would resolve the tension. Unfortunately, such philosophical discussions rarely borrow much from the investigation of actual matter. This is probably largely because actual matter is not (...) continuous, and so it might seem as if discussion of the structure of continuous bodies is merely within the realm of philosophical thought experiments rather than actual scientific investigation. However, classical continuum mechanics models actual matter as if it were continuous, and it has implications about the structure of continuous bodies and about what contact and impenetrability are. This paper describes the relevant notions from classical continuum mechanics so as to resolve the alleged tension between contact and impenetrability. (shrink)
