I. Kant: Cognitive Capacity As a World Structure The empiricism came to the conclusion that the belief that sensory data present the world "as it is" is a tenuous supposition at best. This can be illustrated through the following questions: 1) When I see a brown colour, touch a smooth surface and hear a muffled noise and knock on it with my fingers, these perceptions don't necessarily evoke the concept of a "table". If sense data are the only information coming from the outside world, how does the idea of "things" come into being in our consciousness? 2) Even if we agree with the idea that perceiving things is possible, such perceptions are always subjective. In other words, my perception of so-called "reality" is constrained both by senses and by ability to process information. Supposing I'm blind or deaf, so I can sense some particular aspects of "reality" while ignoring others. Because of that I can sense the world in a different way. So what might lead to us to a conviction that we all see the same table? 3) Can we believe we are living together in the same world or are there as many worlds as people?
