" The most terrifying fact about the universe is not that it is hostile but that it is indifferent; but if we can come to terms with this indifference and accept the challenges of life within the boundaries of death - however mutable man may be able to make them - our existence as a species can have genuine meaning and fulfilment. However vast the darkness, we must supply our own light. "

Stanley Kubrick

" I learned very early the difference between knowing the name of something and knowing something."
