Meaning

Animal faculties are the powers associated with the brain and nerves: sensation, internal perceptual and mental activity, and movement. “Animal” here concerns animate, sentient life and includes human beings. It does not mean merely beast-like behaviour. A “moving faculty” is the power that carries bodily movement into effect; appetite and the bodily instruments through which it works remain distinguishable from it.

Use in the book

Powers, organs and spirits

The anatomical discussion gives the head its animal organs, the brain and the nerves by which sensation and movement reach the body’s other parts. Within that upper region, Burton calls the brain the chief organ serving the animal faculties and the home of memory, judgment and reason. His ventricular account then assigns common sense, imagination, thought and memory to particular chambers. The language moves between a broad region of mental and sensory activity and a more detailed allocation of powers. It should not be narrowed to external sensation alone.

The associated “Animal spirits” are bodily agents in this physiological model. Formed from vital spirits, brought to the brain and distributed through nerves, they give sensation and movement to subordinate members. Faculties name powers; spirits mediate activity; organs are bodily instruments. Burton’s account needs all three roles. The statement that the brain serves a faculty does not turn the faculty into the physical cavity, and the name “spirit” does not make its physiological bearer a ghost.

The sensitive soul is divided into apprehension and movement. Its moving power embraces appetite and change of place; particular bodily motions include the movements of limbs and breathing. Burton also describes internal motion through spirits and pulse. His category is consequently broader than a modern phrase such as “voluntary locomotion” would suggest. The adjoining distinction between natural, sensitive and intellectual appetite further warns that the whole catalogue cannot be confined to acts consciously chosen by a human subject.

An action’s object, directing cause and instruments

The analysis of movement distinguishes what moves, the means by which it moves, and the thing moved. Under the first heading Burton separates efficient cause from end. The end is the object pursued or avoided, illustrated by a dog catching a hare. The efficient cause in a human is reason or imagination subordinate to reason; in a beast the account gives this role to imagination. Imagination moves appetite, appetite moves the moving faculty, and that faculty commands the bodily organ through the spirit’s mediation.

The organs are nerves, muscles and tendons. Their contraction and relaxation draw the joint towards its intended position; the thing moved is the body or a movable member. This sequence keeps the pursued object, the directing power and the instrument apart. Calling the hare a cause in the sense of an end does not make it the bodily mechanism contracting the dog’s muscles. Equally, the nerve’s execution of movement does not make it the faculty that judges the object worth pursuing.

The imagination digression uses a shortened version of this chain to explain sleepwalking. Vapours stir imagination, imagination stirs appetite, and appetite moves animal spirits so that the body walks as though awake. That explanation belongs to Burton’s historical physiology; it also illustrates why “animal” cannot simply mean an act resulting from awake, deliberate choice.

Disturbance and restraint

The causal discussion says that the brain is disordered either in itself or “by consent.” In the latter case, vapours rise from other parts into the head and alter the animal faculties. Consent means physiological connection or sympathy, not the patient’s permission. The neighbouring paragraphs dispute hot and cold causes and introduce heart, liver and stomach. Thus the brain-associated powers may be affected by a disorder whose source lies elsewhere in the body.

A later explanation, attributed to Hercules de Saxonia, makes disordered animal spirits the nearest and immediate causes of symptoms and calls those spirits “immateriall.” Burton follows it with an alternative account based on scorched humours. This reported position should remain visible beside the anatomy’s description of spirits as subtle bodily agents; the book does not present a completely uniform terminology of their substance.

The reverse direction also matters. In the account of passions, imagination communicates an object to the heart and spirits are redistributed. A violent passion can draw spirits away from other parts, impairing their functions: one looks without noticing or hears without attending. The faculties are neither wholly insulated from bodily conditions nor simply passive labels for them; Burton traces interacting processes.

In the treatment section, restraint supplies a practical distinction between desire and execution. Appetite in a fever wants to drink; sore eyes want rubbing; reason forbids it and the moving faculty does not carry out the action. The preceding civil-government comparison distinguishes persuading or moderating emotion from preventing bodily members from obeying it. The moving faculty can therefore be recruited against an appetite without the appetite first disappearing. This is the particular lesson of the examples, which remain historical illustrations rather than current advice about fever or eye care.

Burton’s confidence in restraint must be read beside his argument that inward bodily causes can make melancholy fear persistent. In the elevated-plank comparison, faculties and members obey an impressed image of falling; the next paragraph insists that advice can accomplish little while the bodily causes remain. The vocabulary of government therefore coexists with an account of genuine impairment and limits to immediate control. It should not be turned into the claim that every sufferer can cure distress merely by commanding a faculty to stop.

In this edition

“Animal faculties” is retained, where the Editor note makes its human-inclusive meaning explicit. The same phrase is expanded as “faculties of sensation and movement.” The original paragraph itself proceeds to memory, judgment and reason; the concise modern equivalent should therefore not be mistaken for an exhaustive list of everything Burton associates with the brain.

“Moving faculty” becomes “faculty of movement”. “By consent” becomes “through its connection with other parts”. In the movement analysis, “Cords” becomes “tendons,” while the physiological sense of “spirit” is retained. These are local clarifications of the old account, not substitutions of modern nervous physiology.
