The concept of a homunculus (Latin for "little man", plural "homunculi"; the diminutive of homo, "man") is often used to illustrate the functioning of a system. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. In the scientific sense of an unknowable prime actor, it can be viewed as an entity or agent.

Preformationism,” a theory of heredity, claimed either the egg or the sperm (exactly which was a contentious issue) contained a complete preformed individual called a homunculus. Preformationism is the theory that all Organisms were created at the same time and that succeeding generations grow from homunculi, Animalcules or other Development was therefore a matter of enlarging this into a fully formed being. In the days of preformationism, genetic disease was variously interpreted: sometimes as a manifestation of the wrath of God or the mischief of demons and devils; sometimes as evidence of either an excess of or a deficit of the father's “seed”; sometimes as the result of “wicked thoughts” on the part of the mother during pregnancy. Preformationism is the theory that all Organisms were created at the same time and that succeeding generations grow from homunculi, Animalcules or other .

Homunculus of alchemy

In Carl Jung's studies of Alchemy, he believed the first record of a homunculus in alchemical literature appeared in the Visions of Zosimos, written in the third century AD, although the actual word "homunculus" was never used. Zosimos of Panopolis was an Egyptian alchemist and Gnostic mystic from the end of the 3rd century and beginning of the 4th In the visions, Zosimos mentions encountering a man who impales him with a sword, and then undergoes "unendurable torment," his eyes become blood, he spews forth his flesh, and changes into "the opposite of himself, into a mutilated anthroparion, and he tore his flesh with his own teeth, and sank into himself," which is a rather grotesque personification of the ouroboros, the dragon that bites its own tail, which represents the dyophysite nature in alchemy: the balance of two principles. The Ouroboros (Greek grc Ουροβόρος from grc ουροβόρος όφις "tail-devouring snake" also spelled Ourorboros, Oroborus, Uroboros Dyophysite ( Greek: el δυοφυσῖται is a theological term used in understanding how the divine and human related in the person of Jesus Christ, an area of Zosimos later encounters several other homunculi, named as the Brazen Man, the Leaden Man, and so forth. Commonly, the homunculi "submit themselves to unendurable torment" and undergo alchemical transformation. Zosimos made no mention of actually creating an artificial human, but rather used the concept of personifying inanimate metals to further explore alchemy. [1]

There are also variants cited by other alchemists. One such variant involved the use of the mandrake. Popular belief held that this plant grew where semen ejaculated by hanged men (during the last convulsive spasms before death) fell to the ground, and its roots vaguely resemble a human form to varying degrees. The root was to be picked before dawn on a Friday morning by a black dog, then washed and "fed" with milk and honey and, in some prescriptions, blood, whereupon it would fully develop into a miniature human which would guard and protect its owner. Yet a third method, cited by Dr. David Christianus at the University of Giessen during the 18th century, was to take an egg laid by a black hen, poke a tiny hole through the shell, replace a bean-sized portion of the white with human semen, seal the opening with virgin parchment, and bury the egg in dung on the first day of the March lunar cycle. The University of Gießen (German Universität Gießen) is officially called Justus Liebig-Universität Gießen after its most famous member A miniature humanoid would emerge from the egg after thirty days, which would help and protect its creator in return for a steady diet of lavender seeds and earthworms.

Homunculus of spermists

The term homunculus was later used in the discussion of conception and birth. In 1694, Nicolas Hartsoeker discovered "animalcules" in the semen of humans and other animals. Nicolaas Hartsoeker ( 26 March 1656, Gouda - 10 December 1725, Utrecht) was a Dutch Mathematician Animalcule ("little animal" from Latin animal + the diminutive suffix -culum) is an older term for a microscopic Animal or protozoan This was the beginning of spermists' theory, who held the belief that the sperm was in fact a "little man" (homunculus) that was placed inside a woman for growth into a child. This seemed to them to neatly explain many of the mysteries of conception. It was later pointed out that if the sperm was a homunculus, identical in all but size to an adult, then the homunculus may have sperm of its own. This led to a reductio ad absurdum, with a chain of homunculi "all the way down". Reductio ad absurdum ( Latin for "reduction to the absurd" also known as an apagogical argument, reductio ad impossibile "Turtles all the way down" refers to an Infinite regression Belief about Cosmology, the nature of the Universe. This was not necessarily considered by spermists a fatal objection however, as it neatly explained how it was that "in Adam" all had sinned: the whole of humanity was already contained in his loins. Original sin is according to a doctrine in Catholic theology, humanity's state of Sin resulting from the Fall of Man. The spermists' theory also failed to explain why children tend to resemble their mothers as well as their fathers, though some spermists believed that the growing homunculus assimilated maternal characteristics from the womb environment in which they grew.

Main article: Cortical homunculus

The homunculus is also commonly used to describe the distorted human figure drawn to reflect the relative space our body parts occupy on the somatosensory cortex (sensory homunculus) and the motor cortex (motor homunculus). A cortical homunculus is a physical representation of the Primary motor cortex, i The lateral postcentral gyrus is a prominent structure in the Parietal lobe of the human Brain and an important landmark Motor cortex is a term that describes regions of the Cerebral cortex involved in the planning control and execution of voluntary motor functions The lips, hands, feet and sex organs have more sensory neurons than other parts of the body, so the homunculus has correspondingly distortedly large lips, hands, feet, and genitals. Well known in the field of neurology, this is also commonly called 'the little man inside the brain. '

Homunculus argument or fallacy in the philosophy of mind

A Homunculus argument accounts for a phenomenon in terms of the very phenomenon that it is supposed to explain (Richard Gregory (1987)). Homunculus arguments are always fallacious. The homunculus argument is a Fallacy arising most commonly in the theory of vision. In the psychology and philosophy of mind 'homunculus arguments' are extremely useful for detecting where theories of mind fail or are incomplete.

Homunculus arguments are common in the theory of vision. Imagine a person watching a movie. He sees the images as something separate from himself, projected on the screen. How is this done? A simple theory might propose that the light from the screen forms an image on the retinas in the eyes and something in the brain looks at these as if they are the screen. The Homunculus Argument shows this is not a full explanation because all that has been done is to place an entire person, or homunculus, behind the eye who gazes at the retinas. A more sophisticated argument might propose that the images on the retinas are transferred to the visual cortex where it is scanned. Again this cannot be a full explanation because all that has been done is to place a little person in the brain behind the cortex. In the theory of vision the Homunculus Argument invalidates theories that do not explain 'projection', the experience that the viewing point is separate from the things that are seen. (Adapted from Gregory (1987), (1990)).

Very few people would propose that there actually is a little man in the brain looking at brain activity. However, this proposal has been used as a 'straw man' in theories of mind. A straw man argument is an Informal fallacy based on misrepresentation of an opponent's position Gilbert Ryle (1949) proposed that the human mind is known by its intelligent acts. (see Ryle's Regress). In Philosophy, Ryle's regress is a classic argument against cognitivist theories and concludes that such theories are essentially meaningless as they do not explain He argued that if there is an inner being inside the brain that could steer its own thoughts then this would lead to an absurd repetitive cycle or "regress" before a thought could occur:

"According to the legend, whenever an agent does anything intelligently, his act is preceded and steered by another internal act of considering a regulative proposition appropriate to his practical problem. . . . Must we then say that for the agent's . . . reflections how to act to be intelligent he must first reflect how best to reflect how to act? The endlessness of this implied regress shows that the application of the appropriateness does not entail the occurrence of a process of considering this criterion. " Ryle 1949.

Ryle's theory is that intelligent acts cannot be a property of an inner being or mind, if such a thing were to exist.

The homunculus argument and the regress argument are often considered to be the same but this is not the case. The homunculus argument says that if there is a need for a 'little man' to complete a theory then the theory is false or incomplete. The regress argument says that an intelligent agent would need to think before it could have a thought.

Early literary representations

The idea of the homunculus has proven to be fruitful inspiration. Homunculi can be found in centuries' worth of literature. These literary references have spawned references in modern times in film, animation, video and card games.
