Hume and the Missing Shade of Blue
He first argues that all perceptions of the mind can be classed as impressions or ideas. Here, this would be the idea of the colour blue, and the colour blue itself. Sebastien asked: What point was Hume trying to make with the missing shade of blue in the Treatise of Human Nature? Now I ask, whether it be possible for him, from his own imagination, to supply this deficiency, and raise up to himself the idea of that particular shade, though it had never been conveyed to him by his senses? Hence, perhaps the idea of the missing shade, rather than being a simple idea, would be a complex idea with no corresponding impression. But I believe it well may show exactly what he denied it showed -- viz. He holds that a simple idea is always copied from an antecedent similar impression. It is rather that the character of the phenomenon itself does not clearly run counter to the essential emphasis of Hume's doctrine. What kind of knowledge can we hope for about human beings, and how should we pursue it? The idea here is that just as paints are mixed to produce the range of colour swatches found in a hardware store, so it should be possible for colours to be mixed in the mind in some kind of analogous way.
For if this should be denied, it is possible, by the continual gradation of shades, to run a colour insensibly into what is most remote from it; and if you will not allow any of the means to be different, you cannot, without absurdity, deny the extremes to be the same. In his terminology, it is not a Relation of Ideas an a priori truth which would not necessarily tell us anything about the world, but rather a Matter of Fact contingent truth of which, therefore, the contrary is logically possible. It is perhaps nothing more than the concession that the natural powers of the mind are a little more enterprising than he had allowed for. It is rather that the character of the phenomenon itself does not clearly run counter to the essential emphasis of Hume's doctrine. The problem with this claim is that there needs to be some way of showing that the exception really is limited and will not affect the important general claim that ideas depend on impressions. Hume allows that some simple ideas can be seen to be similar to one another without them sharing anything in common. There is nothing more to an idea than that which can be discerned within it.
What is the purpose of Hume's 'missing shade of blue' thought experiment?
Answering these questions sets the scope and limits of this science. Nelson It is obviously important for Hume's purposes in the Treatise to maintain that simple ideas are always founded in precedent, resembling impressions;1 and he explicitly, over and over, does so, even sometimes being so carried away by this first principle of his science of man T 7 or so careless as to say that not just all simple ideas but all ideas are founded in precedent, resembling impressions. Indeed, even after experiencing the full range of colours a little experimentation will soon show that it is much easier for most people to recognise that there is a missing shade than it is for them to actually form a clear idea of that missing shade. Eastern Daylight Time, rpaul xxxxxxxx writes: Dear Mr Trogge, Let me congratulate you again on your erudition. If it be allowed that the notion of hue can arise through abstraction even though it cannot in any instance be separated from a given example, then it may be fairly argued that the ability to fill a gap in the colour space is quite a different matter to coming up with an isolated idea without any prior impression. I believe it will readily be allowed, that the several distinct ideas of colour, which enter by the eye, or those of sound, which are conveyed by the ear, are really different from each other; though, at the same time, resembling. This being the case it is not necessary to construct an elaborately worked out example; it would be sufficient to say that we might have been constituted differently.
However, what is required of matters of fact is the logical possibility that they could be other than they are, not the practical possibility. These are the Newtonian elements in Smith. Now if this be true of different colours, it must be no less so of the different shades of the same colour; and each shade produces a distinct idea, independent of the rest. See yours in just 2 easy steps! If an eye is presented with a set of predefined colours, then the eye consequently, the person will be able to distinguish the differences between those colours. Hume isn't dismissing the example, as such; it raises a question of importance in his philosophy: the relation between the idea of an impression and the impression itself.
I believe there are few but will be of opinion that he can: And this may serve as a proof, that the simple ideas are not always, in every instance, derived from the correspondent impressions; though this instance is so singular, that it is scarcely worth our observing, and does not merit, that for it alone we should alter our general maxim. This interpretation fits with an overall reading of the work as responding to the epistemological problems that arise in the context of then-contemporary ways of knowledge production. And if it be impossible to assign any, this will serve to confirm our suspicion. If the color blue was never presented to the person before he became blind, would it be possible for the person to create an idea of blue in his mind? But Hume is clear and, it seems to me, serious : colours are simple ideas, the subject imagines has an image of the missing shade, it is an exception to his Principle; and he also appears to recognize that the instance generalizes to other colours and to other sensory modalities. The complex are the contrary to these, and may be distinguished into parts. Now I ask, whether 'tis possible for him, from his own imagination, to supply this deficiency, and raise up to himself the idea of that particular shade, tho' it had never been conveyed to him by his senses? The complex are the contrary to these, and may be distinguished into parts.
Be that as it may, this dissolving of the problem fails to meet the second and third criteria listed above. I've always thought that the missing shade of blue bit was Hume's way of relieving his empiricism of some absoluteness. I asked a similar phrased in a different way on this, and for different reasons; and by some stroke of strange serendipitous fortune I chose the same colour as he did. Let all the different shades of that colour, except that single one, be placed before him, descending gradually from the deepest to the lightest; it is plain, that he will perceive a blank, where that shade is wanting, and will be sensible, that there is a greater distance in that place between the contiguous colours than in any other. Now I ask, whether 'tis possible for him, from his own imagination, to supply this deficiency, and raise up to himself the idea Journal Hume Studies — Hume Society Published: Jan 26, 1989. Indeed, even after experiencing the full range of colours a little experimentation will soon show that it is much easier for most people to recognise that there is a missing shade than it is for them to actually form a clear idea of that missing shade.
It is not an admission of innatism, nor is it a claim that the idea was, as it were, produced out of a hat. Suppose, therefore, a person to have enjoyed his sight for thirty years, and to have become perfectly acquainted with colours of all kinds, except one particular shade of blue, for instance, which it never has been his fortune to meet with. They are all resembling and yet the quality, in any individual, is not distinct from the degree. Hume claims that elementary ideas occurring to one are merely imprints of direct sensory experiences thereof and that the missing shade argument may be a counter-example where the conception of the missing shade of blue is not copied from immediate experience. In this article, the author offers a discussion of the evidential role of the Galilean constant in the history of physics. These resemble each other in their simplicity.

The author argues that measurable constants help theories constrain data. I believe there are few but will be of opinion that he can: And this may serve as a proof, that the simple ideas are not always, in every instance, derived from the correspondent impressions; though this instance is so singular, that it is scarcely worth our observing, and does not merit, that for it alone we should alter our general maxim. He argues: There is however one contradictory phaenomenon, which may prove, that 'tis not absolutely impossible for ideas to go before their correspondent impressions. On the other hand, Nelson suggests the intriguing possibility that far from being an oversight or an embarrassment to his wider project, the missing shade of blue example turns out to be crucial. I believe it will readily be allowed, that the several distinct ideas of colour, which enter by the eye, or those of sound, which are conveyed by the ear, are really different from each other; though, at the same time, resembling.
