“It was all too easy to make things up, it was like skating on thin ice, it was like doing dainty pirouettes on a brittle crust over water thousands of fathoms deep.”

“When we gaze at a star in the Milky Way which is 50,000 light-years away from our sun, we are looking back 50,000 years in time.""The idea is much too big for my little head.""The only way we can look out into space, then, is to look back in time. We can never know what the universe is like now. We only know what it was like then. When we look up at a star that is thousands of light-years away, we are really traveling thousands of years back in the history of space.”

“The stupidest thing she knew was for people to act like they knew all about the things they knew absolutely nothing about.”

“to Hegel, history was like a running river. Every tiny movement in the water at a given spot in the river is determined by the falls and eddies in the water higher upstream. But these movements are determined, too, by the rocks and bends in the river at the point where you are observing it.the history of thought--or of reason--is like this river. The thoughts that are washed along with the current of past tradition, as well as the material conditions prevailing at the time, help to determine how you think. You can therefore never claim that any particular thought is correct for ever and ever. But the thought can be correct from where you stand”

“as Hume expressed it. The mind is 'a kind of theater, where several perceptions successively make their appearance; pass, re-pass, slide away, and mingle in an infinite variety of postures and situations.' Hume pointed out that we have no underlying 'personal identity' beneath or behind these perceptions and feelings which come and go. It is just like the images on a movie screen. They change so rapidly we do not register that the film is made up of single pictures. In reality the pictures are not connected. The film is a collection of instants”

“The German poet Goethe once said that "he who cannot draw on three thousand years is living from hand to mouth." I don't want you to end up in such a sad state. I will do what I can to acquaint you with your historical roots. It is the only way to become a human being. It is the only way to become more than a naked ape. It is the only way to avoid floating in a vacuum.”

“We don't knoe when we're going to make our exits. But one day we'll pass away from this carnival with all its masks and roles, and only a few transient props will remain after us, until they too are swept away. We will step outside time, leave what we call 'reality'.”
