History of Modern Philosophy Essay

1- How, and with what success, does Hume deal with the appargonnt anomaly of the miss trace of blue?In A Treatise of Hu humans Nature, Hume blast to resign 18th century moral philosophy of what he considered to be nonmeaningful and vacuous concepts underlying our theory of cognizeledge be it metaphysical line of reasonings or hypotheses seemingly formulated from the mere imagination of m whatever(prenominal) philosophers. Influenced by the uphill trend of empiricism and naturalistic science kindred Newton and Locke, which Hume owed much(prenominal) of his basic principles from Hume presented the Treatise as an attempt to introduce experimental methods of reasoning into the orbit of moral philosophy. In the origin book of the Treatise, entitled Of the Understanding, Hume devoted the initiative part Of the Origin of our Ideas for explaining the basis of his philosophical system that appeals on the corresponding empiricist approach as that of Lockes.However, curiousl y, Hume had cited an explicit yield-argument the distract of miss weirdy of blue that could invalidate his whole philosophical system that is based on this primaeval principle. Even more puzzling is Humes complacency with this hassle, and although he considers the bother as singular and exceptional, he spaciousy admitted to this reverberation example and did non try to resolve it. Yet, this face merits a deeper investigation, and it is this essays attempt to see whether his apparent complacency with the abstracted step of blue would accommodate any effect on the strength of his philosophical system, and other attempts to engender this problem irrelevant.The problem of the absent fill in of blue by Hume is as follows suppose a man who is rise up acquainted with people of twines for xxx years and has seen every(prenominal) the colours in the set of possible colour spectrum, except for champion limited shade of blue. Then, he is presented with a full spectrum of the shades of blue, from the darkest shade to the darkest, all except the one particular shade in which he has not yet encountered. It is past conceivable that this man would be able to produce this single missing shade of blue. The problem of this lies in the basis of the empiricist philosophy at which Hume is following, namely, that all compositions must be preceded by experience, yet, in this example, it is demonstrated that it is possible for an idea to precede protagonist experience, as the man is able to produce the idea of the missing shade of blue without having first encountered it through his senses.At this point, I would like to voluptuary more on Humes theory of mind and the origin of ideas as that would clarify why this example is so damaging to Humes system. As stated to begin with, Humes project kitty be put into a general label of empiricism, which is a belief that all knowledge comes from experience. a good deal of his line of argument resembles that of L ockes, another prominent empiricist. Hume counterbalance borrowed Lockes tombstone borderinology to a certain extent, with terms like ideas and pictorial matters.Locke believes that ideas are any(prenominal) the mind perceives in itself, or is in the immediate object of perception, thought, or understanding, as when one perceives, forecasts, or understands, the ideas are before the mind. This limits all ideas to be originated from experience (perception), and also shows the connection between thought and perception and their alike(p) nature. The ideas can be divided into ideas of sensation (touch, smell, aspect, etc.) and ideas of reflection (fear, happiness, sadness, etc.), which can hence be separated further into elementary and complex ideas, where complex ideas are derived from simple ones.Hume follows this line of argument with some modifications. He claims he restores the term ideas to its original sense by classifying the objects the mind is perceiving as perceptions , not direct as ideas as Locke confound used, and from perceptions he then distinguished them into impressions and ideas, where they discord in degree, as impressions are more vivid and forceful before the mind, such when sees a colour, and the ideas are more faint, such when one thinks of a colour after having the impressions of it.Hume then induces the distinction of simple and complex ideas, and by introspection, Hume demonstrates that one can think of any simple ideas and then remark corresponding simple impressions that are exact copies of each other, and one can do this with any conceivable simple ideas. Complex ideas are varied in that they are composites of simple ideas.And with this experiment in introspection, Hume then postulates his first dissertation, That all our simple ideas in their first appearance are derivd from simple impressions, which are correspondent to them, and which they exactly represent. We whitethorn call this the reduplicate Principle, as it si mply states that every simple idea is a model of a corresponding impression.One of the most important components of this thesis is the point that its a heritable one in that it shows the origin of ideas as following from impressions as impressions to be the cause of ideas. Again, this is proved by the perpetual conjunction of simple impressions preceding simple ideas, which one can do to every simple idea one may have. Another actualize Hume gives is that of a man born defective of certain perceptive organs, hence, missing certain impressions (e.g. sight or sound), one would not have any ideas of those corresponded with the impressions, for it is evident that deaf people also have great trouble speaking. The genetic component is important in that they validate the empiricism doctrine on the reliance of experience.Anyhow, now we can see how the problem seems to beat the purpose of this thesis. Moreover, a counter example, from a logical standpoint, one counter example is suff icient to turn an argument invalid. So why did Hume not deal with this problem?We may try to take it as Hume claimed the problem to be a singular case where it is not worth expend time on. Being a singular case, one may have to take the argument in closer inspection. Hume states explicitly that the man in question may have enjoyed the sights for thirty years and perfectly well acquainted with all the possible colours except one, and that may be the attempt by him to restrict this to some specific scenario.It is implicitly insert in the counter example that the field of study of this example must be well acquainted with all the colours, such that one can make up colours in ones mind, much like how only musicians of a certain skill level can sight read music. Thus, it appeals to some amount of experience such that one may be bound to experience, habits, or personal background. Yet, when given further consideration, this seems to be invalid as well, as these restrictions do not see m to hold. As far as experience go, a child who does not know what turquoise mean does not necessarily have an idea of the colour turquoise.So this case is certainly not an exceptional case and Hume had not dealt with it satisfactorily. Yet, Humean scholars have tried to find solutions for this problem and some even disregard it as a problem altogether.Firstly, the first objection to this counter argument is that there is no way to test whether the person in question does in fact have an idea of the missing shade of blue before seeing the missing shade or not. there is a great difference between existence able to seat a missing spot in a comp permite spectrum of blue, and being able to produce an idea of the shade of blue without first encountering the impression of it.If ones sees a constant change in shade from, lets say blue-0 where it is darkest to blue-255 where it is the wakefulest shade, then if there is one shade of blue missing, it would be quite noticeable as the mind notices the jump in stepwise and constant change, precisely it does not follow that one could create an idea of that missing shade. To test this is also impossible, as if one is to reproduce colour, it ease does not follow that he produces the idea since he would only be mixing the existing colours to brighter shades, and thus, after finishing mixing the colour, one then has the idea of the colour following the impression. All other shipway of testing is equally futile because they all involve exposing the subject to the missing impression one way or another.Alternatively, if we look at the thesis again, and instead of taking it as a genetic form of the argument that Hume meant it to be, and instead, modifies it close to to a more analytical empiricism form. Humes thesis on the theory of mind, upon closer inspection, can be taken as a form of meaning empiricism, in the sense that ideas to him are the same as different thoughts, which are different kinds of concepts, which is li nked to when one understands something in a linguistic sense one is linking the word with the meaning, or the concepts associated to the word.Hence, if we think of the initial genetic content of the thesis, that impressions strictly precedes ideas, we may relax it slightly in favour of the analogy to meaning empiricism and forget its genetic form and instead formulate the following thesis that all simple ideas must have corresponding conceivable and encounterable impressions. By doing this, we are no longer faced with the problem of the missing shade, since it is perfectly possible that the subject would be able to encounter this particular shade.Lastly, from a personal view, I see the problem of the missing shade of blue as not a problem at all, but Humes mistake lies in classifying colours as simple ideas. It is true that the impressions of light blue baron very well be different than dark blue, so to speak, but to use Humes method, it is possible to separate using our imaginatio n the components light and dark from blue. Thus, it is the impression of blueness which is a simple impression, feature with the impression of light and absent of light that combine to give this great deal of shades of colours. Take this example, suppose some neutral shade of blue, lets number it blue 124, were put somewhere with light, you will be able to see blue 124.However, lets say for some reason, the room becomes lighter, certainly, the shade of blue 124 would have changed to some lighter shade of mayhap blue 200. If we vary the light in the room from darkest to lightest, it is then possible to observe from the darkest to the lightest shade of blue likewise. One may surround that the colour can be calibrated to some objective criteria, perhaps the ratio of pigments of colour blue of some sort, yet, that does not matter since all that matters to Hume is indeed only impression. Furthermore, using this example, we can also say that perhaps the subject of the experiment may h ave in fact encountered the particular shade of blue sometime before without acknowledging it.Conclusively, although Humes treatment of the missing shade of blue is very limited and very complacent, it is perhaps Humes own mistake for considering such example a problem, kinda than the problem itself being a threat to his theory of origins of ideas.
