Doctor Illuminatus Ramon Llull is an amazing figure in the field of philosophy during the Middle Ages, and one of the first people who tried to make logical deductions in a mechanical, rather than a mental way. His method was an early attempt to use logical means to produce knowledge. He demonstrated in an extremely elementary (but nevertheless workable) way that human thought can be described and even imitated by a device. This was a small step towards the thinking machine. But every journey, even the longest, begins with a tiny step.
