"Thinking begins only when we have come to know that reason, glorified for centuries, is the stiff-necked adversary of thought"

In this quote, Martin Heidegger recommends that real believing only begins when we understand that our reliance on factor, which has been applauded and esteemed for centuries, can in fact impede our ability to truly believe. He thinks that factor can be rigid and inflexible, which we require to step beyond reason in order to explore more extensive and meaningful aspects of thinking. He is essentially motivating us to be open to the possibility of believing beyond rationality and to accept more expansive mindsets.
