‘So now let’s sum up. According to Kant, there are two elements that contribute to man’s knowledge of the world. One is the external conditions that we cannot know of before we have perceived them through the senses. We can call this the material of knowledge. The other is the internal conditions in man himself – such as the perception of events as happening in time and space and as processes conforming to an unbreakable law of causality. We can call this the form of knowledge.’
