Accounts of flourishing have been employed in many disciplines. Aristotelian moral philosophers have developed accounts of flourishing based on the characteristic forms of life of living things. In this paper we develop an Aristotelian account of flourishing for living things in general as part of a larger Aristotelian natural philosophy. We relate accounts of flourishing to evolutionary theory, behavioral studies, and ecology as well as to what flourishing is for individual organisms in their parts and activities. We distinguish between contingent and determinate activities by arguing that the behavior of living things are their contingent activities. We consider the structure of cognitive capacities in living things and their relation to flourishing, and we follow out the implications of the distinctively human capacities of cognition. Our consideration of humankind alloww us to show that the study and practice of human flourishing entail stewardship of nature.

Thomists do not have an account of how modern mathematics relates to classical mathematics or more generally fits into the Aristotelian hierarchy of sciences. Rather than treat primarily of Aquinas’s theses on mathematical abstraction, I turn to considering what modern mathematics is in itself, seen from a broadly classical perspective. I argue that many modern quantities can be considered to be, not quantities as such or in themselves, but derived quantities, i.e., quantities that can be defined wholly in terms of the principles of number or magnitude. I also interpret the parts of modern mathematics that study quantitative change as being properly-speaking parts of natural philosophy, for example, probability theory, statistics, calculus, etc. In conclusion, I consider the place that quantity as such has in the order of the world and why we should expect the world to be highly mathematical, as we have found it to be.

Thomists do not have a standard account of history as a discipline or of historical knowledge in general. Since Thomism is a tradition of thought derived in part from historical figures and their works, it is necessary for Thomists to be able to say how we know what we know about those figures and their works. In this paper, I analyze the notion of history both in its key contemporary senses and in how it was used by Aristotle and Aquinas. I show briefly how intellectual knowledge of the past is possible. Then, I argue that the Thomistic tradition implies a far wider notion of history than is generally recognized, history as study of the past in general, not a science in itself, but an aspect of other sciences. Finally, I indicate how this wider notion of history relates to the ordinary sense of history as an inquiry into the specifically human past and then how such an account fits within contemporary Thomism.

Beginning from the apparent failure of Aristotelian natural philosophy in the last centuries, I propose key questions internal to that tradition, most importantly this: Are the central theses of Aristotelian natural philosophy true and do they continue to contribute to our knowledge of the natural world in light of modern discoveries in the sciences? In this paper, I answer this question affirmatively by drawing on the most general mathematical theory used in the sciences to study natural change. I propose an Aristotelian extension of that theory to include substantial change. With such an extension, it becomes possible to see the physical aspect of substantial form, the role that each natural thing plays in making the cosmos what it is. Understood this way, substantial form allows the cosmos itself to be seen in a new way, one that integrates modern scientific discoveries with an Aristotelian approach to nature.
