Citações Marvin Minsky

„It's harmful, when naming leads the mind to think that names alone bring meaning close.“

— Marvin Minsky
Context: Questions about arts, traits, and styles of life are actually quite technical. They ask us to explain what happens among the agents of our minds. But this is a subject about which we have never learned very much... Such questions will be answered in time. But it will just prolong the wait if we keep using pseudo-explanation words like "holistic" and "gestalt." …It's harmful, when naming leads the mind to think that names alone bring meaning close. Ch.2

„If explaining minds seems harder than explaining songs, we should remember that sometimes enlarging problems makes them simpler!“

— Marvin Minsky
Context: If explaining minds seems harder than explaining songs, we should remember that sometimes enlarging problems makes them simpler! The theory of the roots of equations seemed hard for centuries within its little world of real numbers, but it suddenly seemed simple once Gauss exposed the larger world of so-called complex numbers. Similarly, music should make more sense once seen through listeners' minds.

„Only the professional remembers the music itself, timbres, tones and textures.“

— Marvin Minsky
Context: Concrete concepts are not necessarily the simplest ones. A novice best remembers "being at" a concert. The amateur remembers more of what it "sounded like." Only the professional remembers the music itself, timbres, tones and textures.

„I am inclined to doubt that anything very resembling formal logic could be a good model for human reasoning.“

— Marvin Minsky
Context: I am inclined to doubt that anything very resembling formal logic could be a good model for human reasoning. In particular, I doubt that any logic that prohibits self-reference can be adequate for psychology: no mind can have enough power — without the power to think about Thinking itself. Without Self-Reference it would seem immeasurably harder to achieve Self-Consciousness — which, so far as I can see, requires at least some capacity to reflect on what it does. If Russell shattered our hopes for making a completely reliable version of commonsense reasoning, still we can try to find the islands of "local consistency," in which naive reasoning remains correct.

„All intelligent persons also possess some larger-scale frame-systems whose members seemed at first impossibly different — like water with electricity, or poetry with music. Yet many such analogies — along with the knowledge of how to apply them — are among our most powerful tools of thought.“

— Marvin Minsky
Context: All intelligent persons also possess some larger-scale frame-systems whose members seemed at first impossibly different — like water with electricity, or poetry with music. Yet many such analogies — along with the knowledge of how to apply them — are among our most powerful tools of thought. They explain our ability sometimes to see one thing — or idea — as though it were another, and thus to apply knowledge and experience gathered in one domain to solve problems in another. It is thus that we transfer knowledge via the paradigms of Science. We learn to see gases and fluids as particles, particles as waves, and waves as envelopes of growing spheres.

„Looking back in vision is like recapitulation in music; both give us time, at certain points, to reconfirm or change our conceptions of the whole.“

— Marvin Minsky
Context: How do both music and vision build things in our minds? Eye motions show us real objects; phrases show us musical objects. We "learn" a room with bodily motions; large musical sections show us musical "places." Walks and climbs move us from room to room; so do transitions between musical sections. Looking back in vision is like recapitulation in music; both give us time, at certain points, to reconfirm or change our conceptions of the whole.

„A memory should induce a state through which we see current reality as an instance of the remembered event — or equivalently, see the past as an instance of the present.“

— Marvin Minsky
Context: A memory should induce a state through which we see current reality as an instance of the remembered event — or equivalently, see the past as an instance of the present.... the system can perform a computation analogous to one from the memorable past, but sensitive to present goals and circumstances.

„Just knowing that such states exist, that is, having symbols for them, is half the battle.“

— Marvin Minsky
Context: Innate sentic detectors could help by teaching children about their own affective states. For if distinct signals arouse specific states, the child can associate those signals with those states. Just knowing that such states exist, that is, having symbols for them, is half the battle.

„A thing or idea seems meaningful only when we have several different ways to represent it — different perspectives and different associations.“

— Marvin Minsky
Context: What is the difference between merely knowing (or remembering, or memorizing) and understanding?... A thing or idea seems meaningful only when we have several different ways to represent it — different perspectives and different associations.... Then we can turn it around in our minds, so to speak: however it seems at the moment, we can see it another way and we never come to a full stop. In other words, we can 'think' about it. If there were only one way to represent this thing or idea, we would not call this representation thinking.

„In today's computer science curricula … almost all their time is devoted to formal classification of syntactic language types, defeatist unsolvability theories, folklore about systems programming, and generally trivial fragments of "optimization of logic design"“

— Marvin Minsky
Context: In today's computer science curricula … almost all their time is devoted to formal classification of syntactic language types, defeatist unsolvability theories, folklore about systems programming, and generally trivial fragments of "optimization of logic design" — the latter often in situations where the art of heuristic programming has far outreached the special-case "theories" so grimly taught and tested — and invocations about programming style almost sure to be outmoded before the student graduates.

„The "laws of thought" depend not only on the property of brain cells, but also on how they are connected.“

— Marvin Minsky
Context: The "laws of thought" depend not only on the property of brain cells, but also on how they are connected. And these connections are established not by the basic, "general" laws of physics... To be sure, "general" laws apply to everything. But, for that very reason, they can rarely explain anything in particular.... Each higher level of description must add to our knowledge about lower levels. Ch.2

„Every smart person wants to be corrected, not admired.“

— Marvin Minsky
Context: If you like somebody's work -- just go and see them. However, don't ask for their autograph. A lot of people came and asked me for my autograph -- and it's creepy. What I did is read everything they published first... and correct them. That's what they really want. Every smart person wants to be corrected, not admired.

„When you "get an idea," or "solve a problem," or have a "memorable experience," you create what we shall call a K-line.“

— Marvin Minsky
Context: When you "get an idea," or "solve a problem," or have a "memorable experience," you create what we shall call a K-line. This K-line gets connected to those "mental agencies" that were actively involved in the memorable event. When that K-line is later "activated," it reactivates some of those mental agencies, creating a "partial mental state" resembling the original.
