I was not so much referring to ducking, but more to the fact that a fist is solid. I would not call realizing the solidity of a fist a habit.
Well, if you study human babies you will find that they lack an innate fear of most things, they do startle in response to loud noise, but they have no 'natural fear' of most things. So construct that are intuitive, or 'ingrained' are often and usually learned. Such as a fear of height or the response of ducking. These things are learned and conditioned.
So regardless of calling it a habit, conditioning, learned response, it is not innate to humans, and it is learned.
So again we have the triumvirate of personal experience, social conditioning and culture, we learn that 'things' have 'solidity', we are socially conditioned in talking and other's responses and then there is the cultural framework "solid=unchanging'. We are complex to say the least.
Sure, being a forum for skeptics I would expect this to be the case. However implicit in the questioning of common sense is to come up with a more reliable common sense.
Of course solipsism is always the possible outcome for a sceptic, but could hardly be a philosophy embraced by a scientist.
the use of common sense probably has a language barrier, here in the US it often denotes any commonly held belief.
I personally try to avoid its usage, instead referring to the rationale behind it. Solipsism is unavoidable, but then it does not appear to be true.
This is the case were consequences are merely reported. I tend to be more interested in the physical results of introspection, in which case they speak for themselves.
I can't say I follow you here, the physical impacts? certainly not the poorly researched one. So maybe an example?
That may be especially when it comes to verbal communication of the results of introspection. However we need not and in fact mostly do not communicate introspection solely by rational means. We mostly do it through artistic expression. The question then is how much of this expression conveys something meaningful. The best artists tend to convey a common meaning better.
certainly but often the meaning is subjective to the viewer and the responses to artistic expression will vary widely. Any discussion of art will lead you to different conclusions for different viewers. For example in
Moby Dick there is a chapter devoted to Starbuck and his courage. I believe that he has courage and it is not a failure of courage that leads him to not challenge Ahab, this is hotly debated. Or in Wouk's
Caine Mutiny there is a movie version and a made for TV version, in one Queeg is almost craven, in the other he is not.
Then the question remains, without a common objective measure of colour experience, will Mary experience beauty the same way someone with color perception does?
Now that is a great question, I think that Mary can learn to appreciate the values ascribed to beauty, but she will not ascribe them for the same reasons.
Hmm, surely there are cases similar to Mary were we would have recorded a physiological response to a stimulus of which a person is unaware?
I am not sure I follow, are you agreeing that her brain receives the same signals as someone with colour vision or are you saying that her physiological response before the brain would be differently to colours than someone with colour vision?
This is the question that would be unethical to answer.
There are multiple layers to color perception, the photoreceptors, the nerves and network of the retina, the optic nerve, the processing by the visual cortex.
I do not know if her photoreceptors for the longer wave lengths will be active, they likely will be, but she will not have developed )very likely) the retinal structure associated with color vision for the loner wave lengths, especially those where they are contrasted to other photo receptors, will the optic nerves be developed to carry the new signals (unknown) and do they have the capacity to learn them (probably), but the visual cortex and developed and has not had the input from the long wave receptors, so it is likely she will never perceive the 'color red' the way that someone with full color vision would.
But she might, however there does seem to be the issue of developmental cut offs for so many things. She may not.
I am not so sure that it is not relevant. Mary's awareness of colour is not just a matter of her physiology, but also her ability to abstract one from the other. If she has no cultural references to the differences in colour, why would we expect her to abstract one colour from the other just because her physiology can?
That is unrelated to the complete knowledge issue, which is the fallacy of construction I was referring to.
