15. The Theory of Categories

A much read philosopher of the present day (Herbert Spencer) describes the spiritual process, which we carry out in connection with the observation as follows: when in walking through the fields on a September day, we hear a rustling a few steps in front of us, and at the side of the ditch from which it seems to come, we see the grass in movement, we shall probably go straight to the spot in order to learn what has produced the noise and the movement. At our approach a partridge flutters into the ditch, and therewith our curiosity is satisfied: we have what we call an explanation of the phenomenon. This explanation, be it remarked, amounts to the following: since in life we have so often experienced, that a disturbance of the quiet situation of small bodies accompanies the movement of other bodies situated between them, and as we have for this reason generalized the connections between such disturbances and such movements, we regard this special disturbance as explained as soon as we find that it is an example of this very connection! On closer inspection, the matter shows itself to be wholly different from the description given here. When I hear a noise, I first seek the concept for this observation. This concept only points one to something beyond the noise. One who does not reflect further, hears just the noise and is satisfied with that. But my reflection makes it clear to me, that I have to regard the noise as an effect. Thus it is only when I combine the concept of the effect with the perception of the noise, that I am led to go beyond the single observation and to seek for its cause. The concept of the effect calls up that of the cause, and then I seek for the object which causes it, and which I find in the form of the partridge. But these concepts, cause and effect, can never be gained through mere observation, however many cases it should embrace. The observation calls forth the thinking, and it is only this that shows me the way to link the single experience to another.
