“There are more things in heaven and earth, Horatio,” as Shakespeare’s Hamlet says, “than are dreamt of in your philosophy.” He was right. The things that go on in people’s minds are very real and can influence worldly events. In fact, it often seems that they are the only things that can influence the world. After the Great Enlightenment, humanity’s perception of “reality” permanently shifted, never to be the same again. We started to place high values in progress, rationality, science, logic and belief. Our whole modern world is built on them – but there were immense costs involved too.
