"Galileo on the Distinction between Primary and Secondary Qualities (II). The Problem of the Ontological Status of Sensations" The article is a continuation of the paper in which a theoretical analysis of Galileo’s principal argument for the distinction between primary and secondary qualities was provided. It focuses on the problem of the ontological status of secondary qualities/sensations. I discuss three main interpretative approaches to the issue, considered in light of the findings obtained in the first paper. In the first part (...) of the article, I address the mentalist interpretation of Galileo’s secondary qualities. Additionally, I explore the mechanistic rationale behind his account, in virtue of which it may be called ‘the dustbin theory of the sensorium’. In the second part, I examine the arguments for the materialist reading of the secondary qualities and, by contrasting it with the results obtained in the first article, the theoretical problems inherent in it. In the third part of the paper, I discuss the hermeneutical advantages and theoretical disadvantages of interpreting Galileo’s secondary qualities in Aristotelian terms. I conclude the study by indicating the textual basis and historical significance of the interpretative difficulties discussed. (shrink)
