Those, therefore, who look upon intuition as sensation formed and arranged simply according to the categories of space and time, would seem to approximate more nearly to the truth. Space and time (they say) are the forms of intuition; to have an intuition is to place it in space and in temporal sequence. Intuitive activity would then consist in this double and concurrent function of spatiality and temporality. But for these two categories must be repeated what was said of intellectual distinctions, when found mingled with intuitions. We have intuitions without space and without time: the colour of a sky, the colour of a feeling, a cry of pain and an effort of will, objectified in consciousness: these are intuitions which we possess, and with their making space and time have nothing to do. In some intuitions, spatiality may be found without temporality, in others, _vice versa_; and even where both are found, they are perceived by later reflexion: they can be fused with the intuition in like manner with all its other elements: that is, they are in it _materialiter_ and not _formaliter,_ as ingredients and not as arrangement. Who, without an act of reflexion which for a moment breaks in upon his contemplation, can think of space while looking at a drawing or a view? Who is conscious of temporal sequence while listening to a story or a piece of music without breaking into it with a similar act of reflexion? What intuition reveals in a work of art is not space and time, but _character, individual physiognomy._ The view here maintained is confirmed in several quarters of modern philosophy. Space and time, far from being simple and primitive functions, are nowadays conceived as intellectual constructions of great complexity. And further, even in some of those who do not altogether deny to space and time the quality of formative principles, categories and functions, one observes an effort to unite them and to regard them in a different manner from that in which these categories are generally conceived. Some limit intuition to the sole category of spatiality, maintaining that even time can only be intuited in terms of space. Others abandon the three dimensions of space as not philosophically necessary, and conceive the function of spatiality as void of all particular spatial determination. But what could such a spatial function be, a simple arrangement that should arrange even time? It represents, surely, all that criticism and refutation have left standing--the bare demand for the affirmation of some intuitive activity in general. And is not this activity truly determined, when one single function is attributed to it, not spatializing nor temporalizing, but characterizing? Or rather, when it is conceived as itself a category or function which gives us knowledge of things in their concreteness and individuality? [Sidenote: _Intuition and sensation._]
