The hubristic movement

"As the Renaissance progresses, there becomes evident, however, a gradual shift of emphasis from the right hemisphere way of being towards the vision of the left hemisphere, in which a more atomistic individuality characterized by ambition and competition becomes more salient; and originality comes to mean not creative possibility but the right to 'free thinking', the way to throw off the shackles of the past and its traditions, which are no longer seen as an inexhaustible source of wisdom, but as tyrannical, superstitious and irrational – and therefore wrong. This becomes the basis of the hubristic movement which came to be known as the Enlightenment." (The Master and His Emissary, Iain McGilchrist, 2009; page 329).
