If the book is good, is about something that you know, and is truly written, and reading it over you see that this is so, you can let the boys yip and the noise will have that pleasant sound coyotes make on a very cold night when they are out in the snow and you are in your own cabin that you have built or paid for with your work.
If you're reading something from a Nobel Prize-winning physicist next to some guy in his underwear writing in his basement, or his mom's basement, on text, it looks like it's equally plausible.
A learned man is a sedentary, concentrated solitary enthusiast, who searches through books to discover some particular grain of truth upon which he has set his heart. If the passion for reading conquers him, his gains dwindle and vanish between his fingers. A reader, on the other hand, must check the desire for learning at the outset; if knowledge sticks to him well and good, but to go in pursuit of it, to read on a system, to become a specialist or an authority, is very apt to kill what suits us to consider the more humane passion for pure and disinterested reading.
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.)
The genius of reading and of gardening are antagonistic, like resinous and vitreous electricity. One is concentrative in sparks and shocks: the other is diffuse strength; so that each disqualifies its workman for the other's duties.
One can't prescribe books, even the best books, to people unless one knows a good deal about each individual person. If a man is keen on reading, I think he ought to open his mind to some older man who knows him and his life, and to take his advice in the matter, and above all, to discuss with him the first books that interest him.
Be sure then to read no mean books. Shun the spawn of the press on the gossip of the hour. Do not read what you shall learn, without asking, in the street and the train.
The only advice ... that one person can give another about reading is to take no advice, to follow your own instincts, to use your own reason, to come to your own conclusions.
