“To be shaken out of the ruts of ordinary perception, to be shown for a few timeless hours the outer and inner world, not as they appear to an animal obsessed with survival or to a human being obsessed with words and notions, but as they are apprehended, directly and unconditionally, by Mind at Large — this is an experience of inestimable value to everyone and especially to the intellectual.”
The Doors of Perception (1954)

"Man alone, of all creatures of earth, can change his thought pattern and become the architect of his destiny." Actually said by Spencer W. Kimball, twelfth president of The Church of Jesus Christ of Latter-day Saints, in his Miracle of Forgiveness (1969), p. 114. This predates any of the misquotations.
Other forms: "The greatest discovery of my generation is that human beings can alter their lives by altering their attitudes of mind." This is also misattributed to Albert Schweitzer.
James did say: "As life goes on, there is a constant change of our interests, and a consequent change of place in our systems of ideas, from more central to more peripheral, and from more peripheral to more central parts of consciousness."

Context: Man alone, of all the creatures on earth, can change his own patterns. Man alone is the architect of his destiny. The greatest revolution in our generation is the discovery that human beings, by changing the inner attitudes of their minds, can change the outer aspects of their lives … It is too bad that most people will not accept this tremendous discovery and begin living it.

“Never worry about being obsessive. I like obsessive people. Obsessive people make great art”

“A certain degree of neurosis is of inestimable value as a drive, especially to a psychologist.”

“An obsessive creature, constantly dominated by one kind of motive, would not survive.”
Beast and Man: The Roots of Human Nature (1979). 168.
Context: Creatures really have divergent and conflicting desires. Their distinct motives are not (usually) wishes for survival or for means-to-survival, but for various particular things to be done and obtained while surviving. And these can always conflict. Motivation is fundamentally plural. It must be so because, in evolution, all sorts of contingincies and needs arise, calling for all sorts of different responses. An obsessive creature, constantly dominated by one kind of motive, would not survive.
