"Dogs are not like cats, who amusingly tolerate humans only until someone comes up with a tin opener that can be operated with a paw. Men made dogs, they took wolves and gave them human things--unnecessary intelligence, names, a desire to belong, and a twitching inferiority complex. All dogs dream wolf dreams, and know they're dreaming of biting their Maker. Every dog knows, deep in his heart, that he is a Bad Dog..."
"Years later, after other experiences with dogs, I wondered if their species were shaped and charmed to serve as four-legged guides able to assist in leading humanity back to our first-and lost-home. By the example of their joy and humility, by wanting nothing more than food and play and love, by the deep satisfaction that they take from those humble things, they belie all creeds of power and fame. Although they have the teeth to tear, it is by swish of tail and yearning eyes that they most easily get what they want."
"If animals could speak, the dog would be a blundering outspoken fellow; but the cat would have the rare grace of never saying a word too much."
"This may be the primary purpose of dogs: to restore our sense of wonder and to help us maintain it, to make us consider that we should trust our intuition as they trust theirs and to help us realize that a thing known intuitively can be as real as anything known by material experience."

"I accept extinction as best explaining disjoined species. I see that the same cause must have reduced many species of great range to small, and that it may have reduced large genera to so small, and of families."
"I proceed with the proper subject of this discourse; namely, the further changes in scientific belief, which have occurred within my own recollection, even since the time when I first aspired to authorship, now forty- five years ago."
"It was always understood that plants and animals, though completely contrasted in their higher representatives, approached each other very closely in their lower and simpler forms. But they were believed not to blend."
"We may take it to be the accepted idea that the Mosaic books were not handed down to us for our instruction in scientific knowledge, and that it is our duty to ground our scientific beliefs upon observation and inference, unmixed with considerations of a different order."
"Your candor is worth everything to your cause. It is refreshing to find a person with a new theory who frankly confesses that he finds difficulties, insurmountable, at least for the present."
"This substance, which is manifold in its forms and protean in its transformations, has, in its state of living matter, one physiological name which has become familiar, that of protoplasm."
