It is a timely reminder of the role of instinct and faith in our everyday decision making. Sometimes we know something is right even if we can’t prove it. 

How often do we rely on “gut feeling” when making a decision? 

I am not suggesting that we abandon reason and proof but if scientists answering some of the biggest questions facing humankind proceed without proof then we should not downplay the role of instinct and faith in our everyday lives.
