PT - JOURNAL ARTICLE AU - Palkoska, Jan TI - DP - 2013 Mar 30 TA - Aither PG - 98--131 VI - 5 IP - 1 AID - 10.5507/aither.2013.005 IS - 18037879 AB - In this paper, I examine the prospects of the two major views of how to interpret the inesse relation in Spinoza's definitions of substance and mode in the Ethics - the inherence interpretation and the causal interpretation. I argue that these interpretations face a problem in reconciling the claim that modes are in substance with the claim that modes are conceived through substance. I consider a number of strategies that proponents of these readings might use to overcome the problem, and conclude that none is really satisfactory.
