Isn't it the moment of most profound doubt that gives birth to new certainties? Perhaps hopelessness is the very soil that nourishes human hope; perhaps one could never find sense in life without first experiencing its absurdity.

This quote is saying that it is during the times when we are overwhelmed with doubt that new opportunities and ideas appear. It suggests that in order to be able to appreciate the good times, we must also be prepared to experience the bad times. In a way, feelings of hopelessness can help us to appreciate the good times and give us hope for the future. It is only by acknowledging and accepting the absurd moments in life that we can find a greater sense of meaning and purpose.
