Sense perception is one of the classical themes in philosophy. It is traditionally considered a necessary preamble to many important topics, such as the mind-body relationship, consciousness, knowledge, and scepticism. Perception is also a phenomenon which itself raises philosophical questions, such as what is perceptible, what the content of perception is, whether this content is conceptual and how perception is related to epistemic attitudes. While the philosophy of mind and philosophical psychology are the main areas in which perception is dealt with in contemporary philosophy, it is also discussed in the theory of knowledge, cognitive science, philosophical aesthetics and metaphysics. In recent years, the rich tradition of various philosophical theories of perception has been increasingly studied by scholars of the history of philosophy of mind.

The aim of this collection is to shed light on the developments in the theories of sense-perception in medieval Arabic and Latin philosophy, their ancient background and traditional and new themes in early modern thought. Particular attention is paid to the philosophically significant parts of the theories. The articles concentrate on the so-called external senses and related themes. Many of the central ideas are discussed, although the collection is also meant to shed light on less studied subjects.

Zusammenfassung
Sense perception is one of the classical themes in philosophy. Although perhaps not among the most exciting topics, it is traditionally considered a necessary preamble to many of these, such as the mind-body relationship, consciousness, knowledge, and scepticism. This introductory role is not the only reason for the philosophical interest in perception. It is also a phenomenon which raises important questions about what is perceived, how a perceptual experience is caused, what the content of perception is, whether this content is conceptual, how perception is related to epistemic attitudes, and so on. While philosophical psychology is the main area in which perception is dealt with in contemporary philosophy, itis also discussed in the theory of knowledge, cognitive science, philosophical aesthetics and metaphysics. In recent years, the rich tradition of various philosophical theories of perception has been increasingly studied by scholars of the history of philosophy of mind. It may be added that there is of course a large number of scienti c studies of perception in psychology, physiology and contemporary neuroscience.
