Abstract
I show that Aristotle’s ethics is determined by his notion of communities which are in turn determined by hundreds of themes in his Topics-sameness and difference, part and whole, better than, etc. These are tools for all dialectical investigations into being and action for they secure definitions and get at essences of things or their aspects. Reflecting structures of being and good, they allow Aristotle to arrive at objective reality and good. Being tools for all investigations into being and values, we are not free to reject them, nor can we have any discourse or claim to reality or good. I show how permutating the combination of these topics allows for subsequent ‘sub-communities’ which are common to some. I offer an Aristotelian explanation for the origin of these topics and conclude that ethics is determined by communities, which in turn are determined by education.
