PSYCHEDELIC EXPERIENCE AND ITS COGNITIVE FUNCTION Among the features marking a mystical experience facilitated by certain kind of psychedelic substances researchers singled out the so-called noetic quality, which indicates that mystical experiences can have a cognitive significance. The main goal of my article is then to address the question, whether this cognitive capacity of mystical experience has only a subjective/psychological value, or it should be rather treated as a legitimate kind of cognition. The philosophical aspect of this issue enters the (...) domain of ontology and epistemology, since it concerns the question, whether an object of any cognitive experience has to belong to the physical reality, or a proper cognition can be realized in the reality of symbols. In order to deal with these questions I will refer to the philosophy of H.-G. Gadamer. Even though Gadamer did not investigate altered states of consciousness, I believe his hermeneutics can support a hypothesis that altered states of consciousness provide recognition of reality of symbols.

Wittgenstein introduced his claim about colour incompatibility originally in the Tractatus Logico-Philosophicus , where he stated that there could be only one colour in one place and time. It is commonly believed that Wittgenstein abandoned his conception of logical atomism when he realized the consequences of this claim. The aim of this article is to provide an interpretation of the colour incompatibility claim in terms of Wittgenstein’s phenomenology. I will focus on two works of great significance for the claim: Some (...) Remarks on Logical Form and Philosophical Remarks . These two works were written between 1929 and 1930, which is the beginning of the “middle period” in Wittgenstein’s philosophy. I will focus not only on Wittgenstein’s formulation of the colour incompatibility claim, but also on how this claim was justified. The explanation of Wittgenstein’s justification of this claim will help to understand his phenomenology and theory of philosophical grammar. (shrink)

The debates about qualia are common in contemporary analytical philosophy, especially in the area of philosophy of mind or epistemology. Notwithstanding the significance of this notion in present-day investigations, there still appears to be a lack of agreement over how to understand the term “quale”. Due to this fact, our goal is to shed light on the concept of quale as it entered the modern history of philosophy. Strictly speaking, our concern shall be devoted to the American pragmatist philosophy of (...) C. S. Peirce and C. I. Lewis. Therefore, we intend to outline the understanding of quale within Peirce's theory of categories at the beginning, and afterwards we shall present Lewis' remarks on quale in the context of his theory of the given. This approach will not only provide the grounds for relating Peirce's and Lewis' views with each other, but also it will let us interpret Lewis' notion of quale within the pragmatic framework.
