"When the human mind exists in the light of reason and no more than reason, we may say with absolute certainty that Man and all that made him will be in that instant gone"

This quote by Loren Eiseley talks to the fragility of human existence. He suggests that if the human mind were to exist exclusively in the light of reason, with no feeling or intuition, then humanity and all that made it would be entered an immediate. This talks to the significance of emotion and intuition in our lives, as they are necessary components of our mankind. Without them, we would be not able to experience the complete series of life's delights and sorrows. Eiseley's quote works as a reminder of how valuable our humanity is, and how essential it is to welcome our emotions and instinct in order to completely experience life.
