This book is a philosophical analysis of Plotinus' views on sense-perception. It aims to show how his thoughts were both original and a development of the ideas of his predecessors, in particular those of Plato, Aristotle and the Peripatetics. Special attention is paid to Plotinus' dualism with respect to soul and body and its implications for his views on the senses. The author combines a historical approach to his subject, setting Plotinus' thought in the context of thinkers who preceded and succeeded him, with a proper analysis of his ideas and, where appropriate, of those from which they derived.

Plotinus (205-269 AD) is considered the founder of Neoplatonism, the dominant philosophical movement of late antiquity, and a rich seam of current scholarly interest. Whilst Plotinus' influence on the subsequent philosophical tradition was enormous, his ideas can also be seen as the culmination of some implicit trends in the Greek tradition from Parmenides, Plato, Aristotle, and the Stoics.Emilsson's in-depth study focuses on Plotinus' notion of Intellect, which comes second in his hierarchical model of reality, after the One, unknowable first cause of everything. As opposed to ordinary human discursive thinking, Intellect's thought is all-at-once, timeless, truthful and a direct intuition into 'things themselves'; it is presumably not even propositional. Emilsson discusses and explains this strong notion of non-discursive thought and explores Plotinus' insistence that this mustbe the primary form of thought.Plotinus' doctrine of Intellect raises a host of questions that Emilsson addresses. First, Intellect's thought is described as an attempt to grasp the One and at the same time as self-thought. How are these two claims related? How are they compatible? What lies in Plotinus' insistence that Intellect's thought is a thought of itself? Second, Plotinus gives two minimum requirements of thought: that it must involve a distinction between thinker and object of thought, and that the object itselfmust be varied. How are these two pluralist claims related? Third, what is the relation between Intellect as a thinker and Intellect as an object of thought? Plotinus' position here seems to amount to a form of idealism, and this is explored.

Proposes a new way of understanding themes such as matter, knowledge, human happiness and the gods in Epicurus and Plotinus.

Plotinus is the first Greek philosopher to hold a systematic theory of consciousness. The key feature of his theory is that it involves multiple layers of experience: different layers of consciousness occur in different levels of self. This layering of higher modes of consciousness on lower ones provides human beings with a rich experiential world, and enables human beings to draw on their own experience to investigate their true self and the nature of reality. This involves a robust notion of subjectivity. However, it is a notion of subjectivity that is unique to Plotinus, and remarkably different from the Post-Cartesian tradition. Behind the plurality of terms Plotinus uses to express consciousness, and behind the plurality of entities to which Plotinus attributes consciousness (such as the divine souls and the hypostases), lies a theory of human consciousness. It is a Platonist theory shaped by engagement with rival schools of ancient thought.

First published in 1999. We are fortunate in possessing a fascinating document, The Life of Plotinus, written by the philosopher Porphyry, a pupil and associate of Plotinus for the last eight years of his life. The basic facts contained in this Life can be quickly recounted. Plotinus was likely a Greek born in Egypt in AD 205. It is possible, though, that he came from a Hellenized Egyptian or Roman family. In his 28th year, Plotinus discovered in himself a thirst for philosophy. This is a collection of his works- Ennead I contains treatises on what Porphyry calls “ethical matters”; Enneads II–III contain treatises on natural philosophy or cosmology, with some rationalizations for the inclusion of III. 4, 5, 7, and 8. Ennead IV concerns the soul; V Intellect or and VI being, numbers, and the One. The thematic unity of Enneads I, IV, and V is somewhat greater than the rest.

This is the first extensive account of philosophical psychology of perception from ancient to early modern times. The book aims 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.

Plotinus (AD 205–270) was the founder of Neoplatonism, whose thought has had a profound influence on medieval philosophy, and on Western philosophy more broadly. In this engaging book, Eyjólfur K. Emilsson introduces and explains the full spectrum of Plotinus’ philosophy for those coming to his work for the first time. Beginning with a chapter-length overview of Plotinus’ life and works which also assesses the Platonic, Aristotelian and Stoic traditions that influenced him, Emilsson goes on to address key topics including: Plotinus’ originality the status of souls Plotinus’ language the notion of the One or the Good Intellect, including Plotinus’ holism the physical world the soul and the body, including emotions and the self Plotinus’ ethics Plotinus’ influence and legacy. Including a chronology, glossary of terms and suggestions for further reading, Plotinus is an ideal introduction to this major figure in Western philosophy, and is essential reading for students of ancient philosophy and classics.
