We saw in Robinson Crusoe a story of a man pitted against the elements. A man who could use his reason to shape the world to his fashion. To plan carefully, execute based on what you know, and evaluate to improve your practices – these are some of the hallmarks of a conduct based on reason.
In the late 1800s, the turn of the century and the early 1900s we started to see an increasing scepticism and a disenchantment with reason as a solution to man’s problems.

Further down the road there has been talk of intuition, emotional intelligence or lateral thinking – a new kind of reason that might serve us better.
