“What we hear about eternal inflation or the string landscape, seems somehow unavoidably to lead to some kind of multiverse. However, it seems to me there is a fundamental problem there. Once of course you have the multiverse, then you can start playing around and try to find probability or getting to the anthropic principle, or whatever. But the point is that the picture is essentially a classical one, and it is difficult to see that if you have many universes, coming essentially with an inflationary state, that there would not be plenty of horizons in this. Now the quantum mechanics of horizons is, I think, perfectly not understood. The simplest example is the black hole, where after all nobody knows really if the problem lies in the singularity or if it lies really already in the horizon.”

“.. I don’t see any point in simply stating something that is easily available. But then that may just be my own psychology, a kind of negative position. It seems to me that if you avoid everything you can avoid, then you do what you can't avoid doing, and you do what is helpless, and unavoidable. That seems to me more interesting than any other position at this moment – for me anyway.”

“Do parallel universes exist? We don't know, uhm parallel universes are losing favor to the multiverse we have some cogent theoretical expectations that our universe might be just one of many spawned from this, sort of, this hyper-dimensional medium which we'll call the multiverse there's no data to support it but we have good theoretical premise to think that it's there and we have philosophical precedent we used to think Earth was special and unique. It wasn't, we got 8.. 9.. 8 planet we thought the Sun was special it's one of a hundred billion suns, the galaxy's special, no there's a hundred billion galaxies we have one universe or do we? The track record said why should there only be one? be open to the possibility that you don't live in the majority [looking? ] universe that's out there Would a separate universe.. when you say "different universe" slightly different laws of physics which (that's what I'm asking) oh this is the fun part because if you find, if you manage to get a portal to another universe don't be the first one to volunteer to go through because your atoms are working in this universe if a slightly different law of physics.. you could implode, explode come out with three heads who knows?”

“Somehow, suddenly, a musical idea occurs to you; either a whole phrase, or three notes, or a series of chords, something that seems pregnant with possibilities for development. Once you have the kinds of ideas that fascinate you, you're no longer in a position to decide the nature of the animal. It's going to take its essence from the musical ideas that occur to you…. Some musical ideas are too short, they don't seem long enough to carry you through ten minutes of music, so you have to start searching about for other ideas; contrasting ones that seem to fit with the original ones.”

“What the anthropic principle depends upon is the idea that whatever is the nature of the universe, or universe portion that we see about us, being subject to whatever dynamical laws govern its actions, this must be strongly favourable to our very existence.”

“I think so many of the objects we're surrounded by seem trivial. And I think that's because they're either trying to make a statement or trying to be overtly different. What we were trying to do was have a very honest approach and an exploration of materials and surface treatment. So much of what we try to do is get to a point where the solution seems inevitable: you know, you think "of course it's that way, why would it be any other way?"”

Jonathan Ive (1967) English designer and VP of Design at Apple

It looks so obvious, but that sense of inevitability in the solution is really hard to achieve.

“There seems to be some problem about my identity. But no one can find it, because it’s not there—I have lost all interest in having a self. Being a person has always meant getting blamed for it.”

“Suppose two politicians are running for president, and one goes through the farm section and is asked, "What are you going to do about the farm question?" And he knows right away - bang, bang, bang. Now he goes to the next campaigner who comes through. "What are you going to do on the farm problem?" "Well, I don't know. I used to be a general, and I don't know anything about farming. But it seems to me it must be a very difficult problem, because for twelve, fifteen, twenty years people have been struggling with it, and people say that they know how to solve the farm problem. And it must be a hard problem. So the way I intend to solve the farm problem is to gather around me a lot of people who know something about it, to look at all the experience that we have had with this problem before, to take a certain amount of time at it, and then to come to some conclusion in a reasonable way about it. Now, I can't tell you ahead of time what solution, but I can give you some of the principles I'll try to use - not to make things difficult for individual farmers, if there are any special problems we will have to have some way to take care of them," etc., etc., etc.
Now such a man would never get anywhere in this country, I think. It's never been tried, anyway. This is in the attitude of mind of the populace, that they have to have an answer and that a man who gives an answer is better than a man who gives no answer, when the real fact of the matter is, in most cases, it is the other way around. And the result of this of course is that the politician must give an answer. And the result of this is that political promises can never be kept. It is a mechanical fact; it is impossible. The result of that is that nobody believes campaign promises. And the result of that is a general disparaging of politics, a general lack of respect for the people who are trying to solve problems, and so forth. It's all generated from the very beginning (maybe - this is a simple analysis). It's all generated, maybe, by the fact that the attitude of the populace is to try to find the answer instead of trying to find a man who has a way of getting at the answer.”

Ki Sayings (2003)
Context: Until you can clearly make up your mind, you are better off not doing something. Make a habit of being decisive in your daily affairs. Some people can be heard to say, "what will I do if I get killed?!" If you die, there is nothing you can do. Whatever you have to do, do it now, while you are still living. You must practice to be able to return to essential principles at any moment.
