Avicennian essentialism

Essentialism can be defined as a metaphysical theory according to which things have essential and accidental properties. In this paper, I will address Avicennian essentialism, that is, essentialism as we find it in Avicenna's own writings and the writings of the immediate post-Avicennian philosophical tradition of the Islamic world. I will consider a number of primary sources, summarize the state of recent scholarship regarding Avicennian metaphysics of attributes, and I will draw comparisons between Avicennian essentialism and modern essentialism. As a result, I will show that Avicennians endorse two different types of essentialism: conceptualist essentialism and de re essentialism. Avicennian conceptualist essentialism only applies to kinds, while Avicennian de re essentialism only applies to particular individuals.
