To follow Kant one film porno gratis must also understand something about the Scottish philosopher David Hume. Hume had previously submitted
that if one follows the strictest rules of logical induction and deduction from experience to determine the true nature of the world, one must arrive at certain conclusions. His reasoning followed lines film porno gratis that would result from film porno gratis answers to this question: Suppose a child is born devoid of all senses; he has no sight, no hearing, no touch, no smell, no taste...nothing. There's no way whatsoever for him to receive film porno gratis any sensations from the outside film porno gratis world. And suppose this child is fed intravenously and otherwise attended to and kept alive for eighteen years in this state of existence. The question is then asked: Does this eighteen-year-old person have a thought in his head? If so, where does it film porno gratis come from? film porno gratis How does he get it?
Hume would have answered that the eighteen-year-old had no thoughts whatsoever, film porno gratis and in giving this answer would have defined himself as an film porno gratis empiricist, one who believes all knowledge film porno gratis is derived exclusively from the senses. The scientific method of experimentation is carefully controlled empiricism. Common sense today is empiricism, since an overwhelming majority would agree with Hume, even though in other cultures and other times a majority film porno gratis might have differed.
The first problem of empiricism, if empiricism is believed, film porno gratis concerns the
nature of "substance." If all our knowledge comes from sensory data, what exactly is this substance which is supposed to give off the sensory data itself? If you try to imagine what this substance is, apart from film porno gratis what film porno gratis is sensed, you'll find yourself thinking about nothing whatsoever.
Since all knowledge comes from sensory impressions and since there's no sensory impression of substance itself, it follows logically that there is no knowledge of substance. It's just something we imagine. It's entirely within our own minds.
