Abstract

These remarks, which span the last eighteen months of Wittgenstein’s life, extend several of his well known themes from his so-called "later" writings. One such theme, which occurs as a unifying leitmotiv in this work, is that philosophical puzzlement arises from a failure to realize the indefiniteness and complexity of our concepts. Herein it takes the form of the claim that we have not one but several concepts of color. In fact, we have as many concepts of color as we have different methods for determining sameness of color. "The indefiniteness in the concept of color lies, above all, in the indefiniteness of the concept of the sameness of colors, i.e., of the methods of comparing colors". E.g., when I say of two objects that they have the same color I could mean, among other things, that they visually appear to be similar or that their surfaces are painted with similarly tinted paints. Another prominent theme, which runs throughout all of his writings, both early and late, is the employment of a linguistic or grammatical theory of necessity for the purpose of refuting claims to have synthetic a priori knowledge. Herein it is phenomenology which is put in its place, its claims turning out to be only an "analysis of concepts that can neither agree with nor contradict physics". The indefiniteness in our concept of color helps spawn the illusion of such exalted knowledge, because it enables us to use a single sentence, on some occasions, to express a norm or convention of language and, on others, to report experience. "Sentences are often used on the borderline between logic and the empirical, so that their meaning changes back and forth and they count now as expressions of norms, now as expressions of experience". Considerable space is devoted to showing that the sentence "A body cannot seem to be both white and transparent" is used in the former way. While Wittgenstein succeeds in saying many interesting and original things about color, his remarks do not give any further clarification to the underlying themes, such as the two above, which he deploys in this area.—R.M.G.
