Time's passage through the memory is like molten glass that can be opaque or crystalize at any given moment at will: a thousand days are melted into one conversation, one glance, one hurt, and one hurt can be shattered and sprinkled over a thousand days. It is silent and elusive, refusing to be damned and dripped out day by day; it swirls through the mind while an entire lifetime can ride like foam on the deceptive, transparent waves and get sprayed onto the conciousness at ragged, unexpected intervals.
Jacob Bronowski
Progress is the exploration of our own error. Evolution is a consolidation of what have always begun as errors. And errors are of two kinds: errors that turn out to be true and errors that turn out to be false (which are most of them). But they both have the same character of being an imaginative speculation. I say all this because I want very much to talk about the human side of discovery and progress, and it seems to me terribly important to say this in an age in which most non-scientists are feeling a kind of loss of nerve.
