According to Marin Cureau de La Chambre—steering a middleway between the Aristotelian and the Cartesian conception of the soul—everything that lives cognizes and everything that cognizes is alive. Cureau sticks with the general tripart distinction of vegetative, sensitive, and intellectual soul. Each part of the soul has its own cognition. Cognition is the way in which living beings regulate bodily equilibirum and environmental navigation. This regulative activity is gouverned by acquired or by innate images. Natural cognition (or instinct) is cognition by innate images only. Cureau develops a highly originel theory of natural (or 'specialized') instinct. His theory attempts to explain five features of instinct (innateness, specialization, species-specifitiy, coerciveness, teleological nature). According to my interpretation, Cureau proposes a species of what is called a 'teleosemantic theory' of innate cognition.

Cartesian or substance dualism is the view that concrete substances come in two basic kinds. There are material things, such as biological organisms. These may be either simple or composed of parts. And there are immaterial things--minds or souls--which are always simple. No material thing depends for its existence on any soul, or vice versa. And only souls can think.

Bering's analysis is inadequate because it fails to consider past and present adult soul beliefs and the psychological functions they serve. We suggest that a valid folk psychology of souls must consider features of adult soul beliefs, the unique problem engendered by awareness of death, and terror management findings, in addition to cognitive inclinations toward dualistic and teleological thinking.

In the Timaeus , plants are granted soul, and specifically the sort of soul capable of perception and desire. Also in the Timaeus , perception requires the involvement of to phronimon . It seems it must follow that plants are intelligent. I argue that we can neither avoid granting plants sensation in just this sense, nor can we suppose that ` to phronimon ' is something devoid of intelligence. Indeed, plants must be related to intelligence, if they are to be both orderly and good. Plants must have individual souls if they are to be distinguished from each other, each with an orderly life; but the intelligence their perceptions require is not similarly individuated, for their ultimate good is only derivative: it is only as completing the body of the cosmos that plants are good things. Plants have their own perceptions and desires in virtue of the intelligence ordering the cosmos as a whole.

The details of St. Thomas Aquinas’s anthropological view are subject to debate. Some philosophers believe he held that human persons survive their deaths. Other philosophers think he held that human persons cease to exist at their death, but come back into being at the general resurrection. In this paper, I defend the latter view against one of the most significant objections it faces, namely, that it entails that God punishes and rewards separated souls for the sins or merits of something else: the (non-existent) persons to whom those souls once belonged. The objector takes this entailment to be problematic. I argue that it fits in well with St. Thomas’s views about punishment and about persons.

Reflection on death gives rise to a variety of philosophical questions. One of the deepest of these is a question about the nature of death. Typically, philosophers interpret this question as a call for an analysis, or definition, of the concept of death. Plato proposed to define death as the separation of soul from body. This definition is not acceptable to materialists, who think that there are no souls. It is also unacceptable to anyone who thinks that plants and lower animals have no souls, but can die. Others have defined death simply as the cessation of life. This too is problematic, since an organism that goes into suspended animation ceases to live, but may not die.

Bayle's article on Rorarius, author of a work purporting to demonstrate that animals reason better than humans, describes and rejects all but one of the current opinions concerning the souls of animals. That survivor is Leibniz's theory of monads, but Bayle cannot accept pre-established harmony, and so Leibniz goes by the wayside too. Bayle exhibits clearly the consequences of Cartesianism for attempts to distinguish us from the animals. The alternatives are reduced to two: either we do not have an immortal soul, or animals do. Both are untenable on moral grounds. The result for Bayle is that no opinion on animal souls can be stably maintained.

Porphyry's account of the nature of seeds can shed light on some less appreciated details of Neoplatonic psychology, in particular on the interaction between individual souls. The process of producing the seed and the conception of the seed offer a physical instantiation of procession and reversion, activities that are central to Neoplatonic metaphysics. In an act analogous to procession, the seed is produced by the father's nature, and as such it is ontologically inferior to the father's nature. Thus, the seed does not strictly speaking contain a full-fledged vegetative soul. Rather, it acquires its vegetative soul only while it is being actualized by an actual vegetative soul. This actualization takes place primarily at conception, where the seed as it were reverts back and becomes obedient to the mother's nature, but continues through the period of gestation. In this way, Porphyry can account both for maternal resemblance and for ideoplasty. He uses the Stoic language of complete blending to describe the mother's relation to the seed and embryo, and this reveals that he thinks of individuals as having their own unique individual natures (as opposed to sharing in a single universal nature). In the course of developing this theory, Porphyry makes significant revisions to his philosophical predecessors' views in both embryology and botany. He revises Aristotle's verdict on the relative importance of the female in generation as well as Theophrastus' explanation of the biological mechanics of grafting. Although Plotinus nowhere addresses embryology in the same detail as Porphyry does, we can conclude from his remarks on seeds and plants that his own views were similar to those of his student.

Souls play a huge part in the Harry Potter story. Voldemort creates six Horcruxes, thereby dividing his own soul into seven parts, and Harry must destroy all of the Horcruxes before Voldemort can die. At different points in the books, several main characters (Harry, Sirius, and Dudley) narrowly avoid having their souls sucked out of them by a dementor; Barty Crouch, Jr., does not escape this fate. So what is the soul? In Harry Potter’s world, it is clear that people have souls, and that these souls generally survive bodily death. But it is not entirely obvious how souls work and what their nature is. Over the centuries, philosophers and theologians have proposed various different accounts of the soul, and have argued about which is an accurate picture. In this chapter, I will survey some of the major philosophical accounts of the soul before turning to the question of how souls work in Rowling’s books and whether her picture of the soul is plausible.
