IV. The World as Perception

A closer examination gives a very different result from what is described above. When I hear a sound, the first thing I do is to find the concept that corresponds to this observation. It is this concept that takes me beyond the sound. Someone who did not reflect further would simply hear the sound and be content with that. But, because I reflect, it becomes clear to me that I have to understand the sound as an effect. It is therefore only when I connect the concept of effect with the perception of the sound that I am induced to go beyond the single observation and look for the cause. The concept of effect calls up that of cause; I then look for the object which is the cause, and in this case I find it to be the partridge. But these concepts, cause and effect, I can never gain by mere observation, however many instances I may have observed. Observation calls up thinking, and it is thinking that then shows me how to fit one individual occurrence to another.
