all of this is based on our paradigmatic example of a person - a human being, with all the complex legal and moral questions that follow. What else could it be based on? The question is about how far that paradigm can be extended to similar cases, what kinds of similarity are required and how far and under what circumstances extension can go…we are agreed - aren't we? - that there is a real need to separate attribution of beliefs (and hence knowledge?) from articulation of beliefs in language, whether externally, by saying something or internally, by saying something to oneself.
In that case, surely we need to think of explanations of (rational) action as a structure to be completed, rather than a process, whether internal or external. The pratical syllogism is the only paradigm we have for this, so perhaps our question turns into an exploration of that. — Ludwig V
Let me try a hypothesis that links opinion about human-animals differences back to models of embedded beliefs. You mentioned rationality and the syllogism in connection to belief. Many approaches in psychology and philosophy take the propositional statement as their starting point for the understanding of judgement , interpretation , belief and value. I identify with those writers who critique this assumption. Their argument is basically this. Propositions of the form ‘S is P’ and their derivatives indicate that something is or is not the case, that a statement about the world is true or false. This leaves out the fact that when we relate two events we are not just determining what is or is not the case. We are at the same time determining ‘how’ they are the case. Interpretation of events reveals how things seem to us, how they are relevant , how they matter to us, what their significance is in relation to our immediate contextual goals and purposes, how enticing they are.
Even the seemingly most cut and dry statements of truth or falsity show up an aspect of the world in a new way for us, so that it is never simply a matter of something’s being the case or not. Propositional logic is thus not at all the starting point for human belief, it is a narrowly conceived , abstract derivative of basic human interpretive , intentional activity. A much better model of the fundamental ground of cognition and belief is perception. In perceiving anything in our environment, we blend expectations drawn from memory with what is actually in front of us , and synthesize out of that pairing of recollection and anticipation an interpretation of what we are experiencing. Put differently, we believe we are seeing a chair as a result of this mesh of memory, anticipation and actual sensation. Thus all perception involves belief. Not of the propositional form ‘S is P’, but of the hermeneutic form ‘S AS P’. We see something as something, which means we don’t simply regurgitate a copy of something from memory and compare back and forth between this self-same thing and another self-same thing to see if there is a match(truth or falsity). We build our computers to do this computational trick .
We are not computers. Contra Chomsky, we are not computational, representational rationalists. Seeing something as something is recognizing that thing. Recognition is a creative act , not a representational comparison. To recognize a thing is to see it as both familiar and novel in some freshly relevant way. Belief is thus fecund rather than calculative. It is also affective. Things matter to us in affectively valuative ways.
Enactivist psychologists will tell us that we get this way of organizing perceptual interpretation not from an act of God or evolution blessing humans with some unique capacity not available to other animals , but to the basis feature of all living organisms as autopoietic self-organizing systems as functionally unified sense-makers.
Living systems are normatively goal-oriented, and in this sense the are affective and value-forming. They form their own environmental niche and guide and determine the ‘rightness’ of their functioning in their world in accordance with how the feedback from their constructed niche accords or fails to accord with their aims. Thus , all living systems have ‘beliefs’ in that they are purposive in relation to their niche, anticipating forward into their world and adjusting those ‘beliefs’ in relation to feedback from it.
Of course this is along way from human language, but how necessary is language to belief? If belief is a perceptual phenomenon, present in newborns prior to language-learning, then what does language add to belief? I have been arguing that since we are not computers, and belief is not a matter of abstract symbol manipulation like the early cognitive scientists thought , and many on this forum still believe, what language does is allow us to synthesis sources of information from many modalities into words. Animals are also synthesizing many modalities. When a hungry cat hears the can opener, the sound is a form of language that activates the memory of the sight and smell of the food that is in the can, as well as anticipation of the actions of the pet owner that will bring the can of food into the cat’s dish. So a whole sequence of sensations and actions are evoked by the one simple sound of the can opener. It acts as a proto-language. But it will not occur to the cat to reproduce the sound, to share it with others. Why not?
There is substantial limitation to a cat’s memory when it comes to contextually synthesizing in a much more global and complex way a whole range of information that allows humans to share events through language.
So memory is the limiting factor for animals when it comes to language, not some ‘rational’ or ‘propositional’ capability. There are humans with brain injuries which prevent them from holding items in memory long enough to do the ‘S is P’ calculative thing , but they still have language thanks to an overarching ability to remember complex associations.
In sum, in its most basic form, what we call belief is not logical symbol manipulation but the purposive , normative, goal-oriented anticipatory character of perceptual interpretation, which animals share with us. The higher , more abstract forms of belief we achieve through language is unavailable to other. animals due to sever memory limitations. They care about their world and make their way through it on the basis of more temporally constricted , immediate contextual beliefs. They plan, decide and disambiguate within more narrow parameters of time and space.
Some here think only humans are clever enough to figure out what to do with a syllogism. I follow those psychologists and philosophers who think we should take a cue from other animals and be clever enough to get rid of the syllogism as the paradigm of ‘rational belief’.
“For us, agency is about disposition and action, and not about belief. In this we follow the traditions of American Pragmatism and Continental Phenomenology in their critiques of a belief-oriented, representation-centric, model-building mind, in favor of an action-oriented, affordance-centric, world-navigating mind.”(Anthony Chemero)
