...wherever a theory relies on a formulation bearing the logical marks of intentionality, there a little man is concealed. — Daniel Dennet, 1978

From the Incomplete Nature glossary:
Homunculus: Any tiny or cryptic human-like form or creature, something slightly less than human, though exhibiting certain human attributes. In recent scientific literature, “homunculus” has also come to mean the misuse of teleological assumptions: the unacknowledged gap-fillers that stand behind, outside, or within processes involving apparent teleological processes, such as many features of life and mind, and pretend to be explanations of their function
From Wikipedia: Homunculus
Homunculus (masculine, Latin for "little man", plural: "homunculi"; from the diminutive of homo) is a term used, generally, in various fields of study to refer to any representation of a human being. Popularized in sixteenth century alchemy and nineteenth century fiction, it has historically referred to the creation of a miniature, fully formed human. The concept has roots in preformationism as well as earlier folklore and alchemic traditions. Currently, in scientific fields, a homunculus may refer to any scale model of the human body that, in some way, illustrates physiological, psychological, or other abstract human characteristics or functions.

Topics covered: psychology, humanities
Parable: If there is the little man that looks like Einstein standing at a control panel inside the brain, then there would have to be a little man inside his head. p45-46
Homunculus: a form of explanation offering a mechanistic account of some living or mechanical phenomena, but instead only appeals to another cryptically equivalent process at some lower level. p46
Lower level components are often no simpler. Recursion is not an answer. The use of an homunculus postpones the full analysis. p47
B F Skinner and Behaviorism: motivation: avoid mental concepts in explaining why we act the way we do. Invoking mental states, such as beliefs and desires, assigns major parts of the explanation of human behavior to unobservable and unanalyzed causes. p47
B F Skinner and Behaviorism: first attempts designed to avoid the homunculus fallacy - though their cure worse than bite. p48
Familiar example of an homunculus : Wizard's image in Wizard of Oz. p48
Exposed homunculus: reveals little, but leaves you wiser. Nothing gets explained but the trick itself

The term homunculus ('little man') has a lengthy history. p50
Homunculus in:
Preformationism - the form was already present in some minimal way, offered a materialist/mechanistic solution to development. p50
But: does not answer where the minimal form itself came from. p50
Neurologists create images that map the brain to specific regions of the body. p50
Maps are representations not the territory. Similar but not intrinsically meaningful. The 'reader', is extrinsic. p51
We need to know about the process of interpreting. Homunculus are unacknowledged gap-fillers. Can impede our efforts - p52
Koch and Crick / Butler Erewhon: invoke an homunculus. p52
Homunculus ancestors were the gods and fairies. - p53
Homunculus in science today leads to misleading explanations, gap-fillers that obscure, gremlins that mask - p53
Aristotle's notion of entelechy - a formative principle that tends to realize itself - goal-directed. p53
Vitalism / élan vital are homucular at their core - p55
Homunculus is:
The thing that the homuculus has is that it has a life of its own. p55
This section:
Key words: homuculus, [page:Ententional Ententional], final cause
Topics covered: philosophy
The homunculus is a challenge for science. It is the marker for what is not there, the ententional. p55
Homunculus not recognized, hidden, forgotten - not recognized for being placeholders This tendency perhaps derives from the familiarity of also not knowing the thoughts and motivations of the people around us. p56
The ententional gets forgotten. p56
The incredible shrinking homuculus. Science provides more & more mechanistic explanations. Extrapolate and the homuculi all get replaced by complex mechanical explanations. [Go to zero?] p56
Why do ententional explanations tend to get eliminated?
Teleological explanations point to a locus or origin but leave the mechanism of causal efficiency incomplete.
This it is difficult to ascribe energy, materiality or physical extension to the ententional. p57
In this age of 'life is just chemistry', there is still no explanation on the origins of life and consciousness. Saying there are explanations is premature. p57
The homunculus symbolizes what science still cannot explain. The 'black box'. They are markers and can offer clues. p58
This section:
Key words: Aristotle, final causality
Topics covered: philosophy
In history: the homunculus is a placeholder for Aristotle's 'final causality'. p58
All designed objects exist in futuro and are thus incomplete. p59
Final causality is logically incoherent. Thought is a possible future and has no material existence - and is essentially homuncular. p59
Today, in science: The term homunculus has become pejorative - often applied to errors in thinking.
But it is OK to use the homuculus, provisional homunculi, as a marker for unfinished business. - as long as there is full disclosure, recognized for what they are, and slated for replacement ASAP. p60

Topics covered: humanities, philosophy
Intelligent Design(ID) - inherits homunculus assumptions. p61
ID: certain structures are irreducibly complex. p61
If the mechanistic theory is incomplete, should you bring in the humunculi? p61
ID:the black box you are never allowed to open. p62
Allow the demons to enter and science falls apart. p62
People mix the incompatible. Homunculi get smuggled in. p63
Homunculus argument: ententional property presumed to be explained by its existence and its inexplainability. p63
Molière/La Malade Imaginaire: Homunculus not an explanation, but an evasion. p64

Key words: Epigenetics, Preformationists, Élan vital, Sensationalism [Sensualism?], Erasmus Darwin, Jean-Baptiste Lamark, Charles Darwin, Ernst Haeckel
Topics covered: biology
History of theories of the development of cell form
Preformationist: material / at least some form of form is present from the get-go. p64
Epigenisis: intangible / form not materially present at conception. Form acquired and shaped by some intangible influence. p64
Arguments against epigenesis: p65
Arguments against Preformationism: Which came first? The chicken? Or the egg? p65
Erasmus Darwin: Sensationalism - form came from the environment/the womb - another aborted theory. p66
Lamark offered a middle ground: plans of cell were inherited, but modified by circumstance. p67
Darwin's natural selection: added tweaks and disembowels the concept of preformation. Offers a homunculus free theory of cell-development.
But natural selection has little to say directly about the development of cell form.
Ernst Haeckel postulated: p67
Present considerations on the development of form
Both concepts contributed to the progress in our current understanding of cell development, p68
The term Epigenesis now used to describe extragenomic contributions to cell form. p69
The information to create an organism is recreated each time a new organism comes into existence. p69

Key words: Universal grammar, Noam Chomsky, Steve Pinker, Roger Bacon, William of Occam, Jerry Fodor
Topics covered: linguistics, philosophy
Noam Chomsky/Universal grammar: may be a homuncular theory. p69
Language is dependent on structures in the brain that are much older than the brain. p70
- and it may not be the only game in town.
Universal grammar: It's a map, not the territory itself. p70
Pinker (also Bacon, Occam and Fodor): 'mentalese' is a homunculus. p71
By ignoring the problems of explaining the representation and interpretation, these theories shift the mysteries of language from psychology and linguistics to evolutionary biology and neuroscience. But language has intentional properties, whereas brain structures do not. p72

Key words: Stephen Hawking, 'turtles all the way down', Panpsychism, Niels Bohr, Werner Heisenberg, Seth Lloyd, Anthropic principle, Alfred North Whitehead, Prehension, Concresence
Topics covered: philosophy, cognitive science
Parable: 'But it's turtles all the way down! p72
Panpsychism - attenuated mental attributes inherently everywhere. A vestige of mental phenomenology is present in every event, suffused through the cosmos. p73
Can ententional phenomena be viewed as panpsychic? p73
Bohr: events lack existence unless they are observed. p73
Seth Lloyd: universe as an immense quantum computer. p74
Computation began with the Big Bang. p74
Lloyd uses restricted definition of information. p75
Anthropic principle - we are here only because a handful of physical constants are precisely balanced and tuned p76.
There could have been many other failed universes/Big Bangs. Or the universe might be self-organizing. p76
Whitehead/Prehension - processes with tendencies. p77
Whitehead has some good bits - but does not explain the difference/the separation between organic and inorganic. p78
Panpsychism does not well explain how the processes of life and mind differ so radically from the rest of physics. p79
