Today is Hegel’s birthday. To mark that here is a quote from the start of Encyclopedia:
The Content, of whatever kind it be, with which our consciousness is taken up, is what constitutes the qualitative character of our feelings, perceptions, fancies, and ideas; of our aims and duties; and of our thoughts and notions. From this point of view, feeling, perception, etc., are the forms assumed by these contents. The contents remain one and the same, whether they are felt, seen, represented, or willed, and whether they are merely felt, or felt with an admixture of thoughts, or merely and simply thought. In any one of these forms, or in the admixture of several, the contents confront consciousness, or are its object. But when they are thus objects of consciousness, the modes of the several forms ally themselves with the contents; and each form of them appears in consequence to give rise to a special object. Thus what is the same at bottom may look like a different sort of fact.
The several modes of feeling, perception, desire, and will, so far as we are aware of them, are in general called ideas (mental representations): and it may be roughly said that philosophy puts thoughts, categories, or, in more precise language, adequate notions, in the place of the generalised images we ordinarily call ideas. Mental impressions such as these may be regarded as the metaphors of thoughts and notions. But to have these figurate conceptions does not imply that we appreciate their intellectual significance, the thoughts and rational notions to which they correspond. Conversely, it is one thing to have thoughts and intelligent notions, and another to know what impressions, perceptions, and feelings correspond to them.
