Avicenna's notorious claim that God knows particulars only 'in a universal way' is argued to have its roots in Aristotelian epistemology, and especially in the "Posterior Analytics". According to Avicenna and Aristotle as understood by Avicenna, there is in fact no such thing as 'knowledge' of particulars, at least not as such. Rather, a particular can only be known by subsuming it under a universal. Thus Avicenna turns out to be committed to a much more surprising epistemological thesis: even humans (...) know particulars only in a universal way. (shrink)

God is omniscient; therefore, He knows that ‘the flower in my hand is red.’ If God knows that ‘the flower in my hand is red,’ then He knows it perceptually. God does not know anything perceptually. It is clear that the set of propositions – form an inconsistent triad. This is one of four problems with which Avicenna was engaged concerning God's knowledge of particulars, which I call the problem of perceptual knowledge. In order to solve PPK and three other (...) problems, Avicenna has developed a theory concerning God’s knowledge of particulars. Secondary literature around Avicenna’s theory of God’s knowledge of particulars has mostly directed its attention to give an account of Avicenna’s positive theory rather than the problems which that theory was designed to solve. But this paper will not do the same thing as this secondary literature. In contrast, in this paper, I will concentrate on the characterization of one of the problems, i.e., PPK, because of which Avicenna has presented his positive theory of God’s knowledge of particulars. In short, this paper aims to show why Avicenna deems explaining God’s knowledge of, say, the redness of a flower, via his accepted theory of perception as problematic. In this regard, I will extract three versions of PPK based on Avicenna's philosophy and through it will shed some light on Avicenna’s theory of God’s knowledge of particulars. (shrink)

(i) God is omniscient; therefore, for any change, C, among particulars, God knows the occurrence of C. (ii) If God knows the occurrence of C, then X. (iii) not-X. It is clear that the set of propositions (i)—(iii) is inconsistent. This is the general form of two problems—which I call the ‘problem of change in knowledge’ (PCK) and the ‘problem of change in essence’ (PCE)—for Avicenna concerning God’s knowledge of particulars. No work in the secondary literature has discussed exactly what (...) PCK and PCE are. In this paper, I will clarify exactly what they are. (shrink)

Omniscience is the divine attribute of possessing complete or unlimited knowledge. This article examines motivations for taking such a property to be a divine attribute, attempts to define or analyse omniscience, possible limitations on the extent of divine knowledge, and, finally, objections either to the coherence of the concept or to its compatibility with other divine attributes or with widely accepted claims.
