Thales of Miletus was a philosopher who lived about 600 years before the common era on the coast of what is now Turkey. He was the leader of what was then a new school of thought that promoted using observation to understand the world around us. He was reputed to have predicted a full eclipse in 585 BCE. From observation, Thales deducted that weather conditions, not appeals to the gods, lead to a good harvest. Predicting a high yield of olives one year, he is said to have bought up all the local olive presses, then profited by renting them out to meet increased demand. We can often look back at the beliefs of people from the past and see how the things they thought of as supernatural were quite natural after all. Sometimes, faith in the supernatural can result in a lack of curiosity about the natural. When someone finally discovers the truth the result is growth and a better understanding of the world in some cases. Do you think that faith in the supernatural has limited human development or are there examples of how humanity improved its lot due to belief in supernatural control of the world?
