Appealing to some analytic tools developed by contemporary analytic philosophers, I discuss Avicenna’s views regarding the problem(s) of linguistic and mental reference to non-existents, also known as the problem(s) of ‘empty intentionality’. I argue that, according to Avicenna, being in an intentional state directed towards an existing thing involves three elements: (1) an indirect relation to that thing, (2) a direct relation to a mental representation of that thing, and (3) a direct relation to the essence of that thing. Empty (...) intentionality does not involve the first element. Moreover, depending on the nature of the non-existent we are thinking about, the third element may not be involved either. Thus, the necessary element of being in an intentional state towards something is to be related to a mental representation of that thing. The nature of this representation may vary depending on the nature of the non-existent towards which our thought is directed. (shrink)

Al-Ghazālī's most detailed explanation of how signification works occurs in his treatise on The Beautiful Names of God. Al-Ghazālī builds squarely on the commentary tradition on Aristotle's Peri hermeneias : words signify things by means of concepts and correspondingly, existence is laid out on three levels, linguistic, conceptual, and particular (i.e. extramental). This framework allows al-Ghazālī to put forward what is essentially an Aristotelian reading of what happens when a name successfully picks out a being: when a quiddity is named (...) by some kind term, its referent in the mind is formally identical to the quiddity of an individual existent which belongs to that natural kind. Al-Ghazālī then proceeds to tease out the implications of this scheme for the special problem of signifying God. It turns out that the Peripatetic theory, which al-Ghazālī appropriates from Ibn Sīnā, is ill equipped for the task as al-Ghazālī envisions it. (shrink)

This dissertation examines Avicenna's theory of efficient causation in light of his approach to central problems in metaphysics, from the proof of the Necessary Existent to his emanative cosmology. Avicenna provides an internally coherent metaphysical account of efficient causation. A metaphysical account of the efficient cause explains the existence of the effect or essence in a way that is not explained by the causes of motion, as investigated in physics. That is, a full explanation of the cause of the existence (...) of an essence is not found in the four causes of natural change and motion. Avicenna aims to clarify what the explanatory division of labor is between the account of the natural philosopher and that of the metaphysician. In so doing, Avicenna develops a theory of causation that ties his innovative concepts of the contingent in itself and necessary in itself to the concept of efficient causation. A central distinction that Avicenna advances in relation to the efficient cause is that between the cause of the effect qua species and the cause of the effect qua individual. The distinction is relevant to understanding his view of the role of the causes of the essence, including the Active Intellect. Drawing on the above theory of efficient causation, the study reexamines Avicenna's famous proof for the Necessary Existent. The analysis shows that his metaphysical account of efficient causation is at the heart of his proof for a Necessary Existent. The "cause of persistence", in particular, is argued to have a more critical role than previously acknowledged, and is explicated in the context of his theory of efficient causation in metaphysics.
