Grace de Laguna’s philosophical work was bold and original. She was also able to connect together seemingly disparate strands of the pragmatic, metaphysical and psychological research going on around her, as Joel Katzav shows in his paper. This commentary gives some historical background to her academic career in an attempt to explain how she could have been forgotten as a philosopher. Social and institutional factors led to her work not being recognized when she wrote and thus sinking into obscurity in philosophical circles afterwards. Although her work was initially widely read, her research seems not to have had any continuing direct impact on later developments in philosophy. However, it is crucial to restore her thought to its rightful place in the history of our subject.

This paper aims to establish that, for Aristotle, the state of the physical body is crucial to the human capacity for theoretical understanding. In recent years, scholars have begun to recognise the importance of Aristotle’s biological writings for understanding his psychology, after the relative neglect of these connections. The relevance in particular of the so-called Parva naturalia, small works on what is common to body and soul, and the De motu animalium, a work devoted to animal motion in broad terms, has begun to fill in the picture of how the living body is involved in cognition. This paper will support this point of view by adding the De generatione animalium, a work which gives an account of the advent of soul capacities through the development of the body from the blood, under the control of the nutritive soul. An Aristotelian science of human physiology is a study of the “thinking body”, a person as a whole rather than disembodied nous. I will first set out factors that have made it difficult to integrate Aristotle’s biological treatises into our understanding of human thinking. Next, I will distinguish the thinking shared with other animals, from theoretical understanding, which is something only humans can achieve. I will then explain the aspects of the body that must facilitate and eventually bring about the capacity for thinking, before turning to Aristotle’s embryology where nutritive soul is ultimately responsible for the construction and maintenance of the thinking body. It will be concluded that only a human body leads to theoretical understanding and only a healthy human body can do so adequately.
