ABSTRACT. The main objective of this paper is to explore and describe Descartes’s independence conception of substance, Locke’s conception of material substance, the original Aristotelian theory of substance, and Brentano’s ontology of substance and accident. Scholarly research reveals strong correlations between Spinoza’s view of God as the substance of all creatures, Descartes’s subject conception of substance, the Brentanian picture of the relation between substance and accident, and Aristotle’s conception of the relation of whole and part. pp. 135–140

Keywords: substance, Aristotle, Locke, Descartes, Spinoza, Brentano
