1. "Writing something down cannot change in any significant way our mental representation of it, for it is the mental representation that gives birth to the written form, not vice versa."
- Mary Carruthers, The Book of Memory: A Study of Memory in Medieval Culture
2. "People who learn to extract the key ideas from new material and organize them into a mental model and connect that model to prior knowledge show an advantage in learning complex mastery. A mental model is a mental representation of some external reality."
- Peter C. Brown, Make It Stick
3. "Inflation is taxation without representation."
- Quote by Milton Friedman
4. "We have seen that experience depends on the way we invest psychic energy—on the structure of attention. This, in turn, is related to goals and intentions. These processes are connected to each other by the self, or the dynamic mental representation we have of the entire system of our goals. These are the pieces that must be maneuvered if we wish to improve things."
- Mihaly Csikszentmihalyi, Flow
5. "No subject was more perfectly suited to the loosened formal framework and swift juxtaposition of disparate elements that marked his ‘totally chromatic’ style; and it is generally agreed that in this Representation of (mental) Chaos that style found its most impressive outlet. But a representation is not a transcription. The music itself is not chaotic. There is a willed unity of atmosphere, created through a myriad intensely visualized details, which could only be achieved under iron control. Paradoxically, this is probably the direct result of the spontaneity and intensity with which Schoenberg must have been composing in order to have created the work in such a short space of time. The monodrama possesses no clearly deﬁned structure, ranging so freely and juxtaposing lyricism, violence, and Angstridden terror in such uncompromising combination that it attains an effect of continuous high-pressure improvisation; yet it combines this with a powerful sense of continuity and tragic"
- Malcolm MacDonald, Schoenberg
6. "The word God has become empty of meaning through thousands of years of misuse. I use it sometimes, but I do so sparingly. By misuse, I mean that people who have never even glimpsed the realm of the sacred, the infinite vastness behind that word, use it with great conviction, as if they knew what they are talking about. Or they argue against it, as if they knew what it is that they are denying. This misuse gives rise to absurd beliefs, assertions, and egoic delusions, such as My or our God is the only true God, and your God is false, or Nietzsche’s famous statement God is dead. The word God has become a closed concept. The moment the word is uttered, a mental image is created, no longer, perhaps, of an old man with a white beard, but still a mental representation of someone or something outside you, and, yes, almost inevitably a male someone or something."
- Eckhart Tolle, The Power of Now: A Guide to Spiritual Enlightenment
8. "EVERY PIECE OF KNOWLEDGE MUST HAVE A SINGLE, UNAMBIGUOUS, AUTHORITATIVE REPRESENTATION WITHIN A SYSTEM."
- Andrew Hunt, The Pragmatic Programmer: From Journeyman to Master
