In company with people of your own trade you ordinarily speak of other writers' books. The better the writers the less they will speak about what they have written themselves. Joyce was a very great writer and he would only explain what he was doing to jerks. Other writers that he respected were supposed to be able to know what he was doing by reading it.
Oh! it is absurd to have a hard-and-fast rule about what one should read and what one shouldn't. More than half of modern culture depends on what one shouldn't read.
I have sometimes dreamt ... that when the Day of Judgment dawns and the great conquerors and lawyers and statesmen come to receive their rewards -- their crowns, their laurels, their names carved indelibly upon imperishable marble -- the Almighty will turn to Peter and will say, not without a certain envy when He sees us coming with our books under our arms, "Look, these need no reward. We have nothing to give them here. They have loved reading.
I think I have done well, if I have acquired a new word from a good author; and my business with him is to find my own, though itwere only to melt him down into an epithet or an image for daily use.
There exists a law, not written down anywhere but inborn in our hearts; a law which comes to us not by training or custom or reading but by derivation and absorption and adoption from nature itself; a law which has come to us not from theory but from practice, not by instruction but by natural intuition. I refer to the law which lays it down that, if our lives are endangered by plots or violence or armed robbers or enemies, any and every method of protecting ourselves is morally right.
I am so convinced of the advantages of looking at mankind instead of reading about them, . . . that I think there should be a law amongst us to set our young men abroad for a term among the few allies our wars have left us.
When I examine myself and my methods of thought, I come to the conclusion that the gift of fantasy has meant more to me than my talent for absorbing positive knowledge. (Reading this makes me wonder how much sooner man could have walked on the moon... had we listened to a child's fantasies. It is truly a pity that so many lose their gift of imagination to the steady hum of the status quo.)
Neither is a dictionary a bad book to read. There is no can't in it, no excess of explanation, and it is full of suggestion, the raw material of possible poems and histories.
