"The essence of optimism is that it takes no account of the present,
but it is a source of inspiration, of vitality
and hope where others have resigned;
it enables a man to hold his head high,
to claim the future for himself and not to abandon it to his enemy"
Dietrich Bonhoeffer (1906-1945)
I have found the quote in the book: Ten Thoughts About Time: A Philosophical Enquiry by Bodil Jonsson
