[A dragonfly larva is] carrying inside it two entirely separate blueprints, two different programmes [to turn into a dragonfly].

Question: Account for the delicate shades of colour sometimes seen on the inside of an oyster shell. State and explain the appearance presented when a beam of light falls upon a sheet of glass on which very fine equi-distant parallel lines have been scratched very close to one another.
Answer: The delicate shades are due to putrefaction; the colours always show best when the oyster has been a bad one. Hence they are considered a defect and are called chromatic aberration.
The scratches on the glass will arrange themselves in rings round the light, as any one may see at night in a tram car.

A Native American elder once described his own inner struggles in this manner: Inside of me there are two dogs. One of the dogs is mean and evil. The other dog is good. The mean dog fights the good dog all the time. When asked which dog wins, he reflected for a moment and replied, The one I feed the most.

A school is a building which has four walls and tomorrow inside.

Champions aren’t made in gyms. Champions are made from something they have deep inside them—a desire, a dream, a vision. They have to have last-minute stamina, they have to be a little faster, they have to have the skill and the will. But the will must be stronger than the skill.

Crystals grew inside rock like arithmetic flowers. They lengthened and spread, added plane to plane in an awed and perfect obedience to an absolute geometry that even stones—maybe only the stones—understood.

Education consists in co-operating with what is already inside a child's mind … The best way to learn geometry is to follow the road which the human race originally followed: Do things, make things, notice things, arrange things, and only then reason about things.

I find myself now preaching about the golden age of manned spaceflight, because something went on there, within us, that we’re missing. When we went to the Moon, it was not only just standing on a new plateau for all mankind. We changed the way everybody in the world thought of themselves, you know. It was a change that went on inside of us. And we’re losing that.

I remember asking an adult, “What goes on inside a cocoon?” and he said, “The caterpillar is totally broken down into a kind of soup. And then it starts again.” And I remember saying, “That can’t be right.” As a procedure, you can’t imagine how it evolved.

I think we all have a little voice inside us that will guide us. It may be God, I don’t know. But I think that if we shut out all the noise and clutter from our lives and listen to that voice, it will tell us the right thing to do.

I’ve never consciously tried to keep myself out of anything I write, and I’ve always talked clearly when people interview me. I don’t think my life is too interesting. It’s lived mainly inside my brain.

It is not enough that a few brilliant men can create computers to “think” for us; for the greatest thinking machine is inside each of us.

Learning how to access a continuity of common sense can be one of your most efficient accomplishments in this decade. Can you imagine common sense surpassing science and technology in the quest to unravel the human stress mess? In time, society will have a new measure for confirming truth. It’s inside the people-not at the mercy of current scientific methodology. Let scientists facilitate discovery, but not invent your inner truth.

Nonconformists travel as a rule in bunches. You rarely find a nonconformist who goes it alone. And woe to him inside a nonconformist clique who does not conform with nonconformity.

Nothing can be inside an edgeless universe.

On each of two porches lie big chunks of serpentine—smooth as talc, mottled black and green. When you see rocks like that on a porch, a geologist is inside.

Quarks appear to be without spatial extent and to lack a deeper structure: they have character without extension and are substance without inside.

Standing now in diffused light, with the wind at my back, I experience suddenly a feeling of completeness–not a feeling of having achieved something or of being stronger than everyone who was ever here before, not a feeling of having arrived at the ultimate point, not a feeling of supremacy. Just a breath of happiness deep inside my mind and my breast. The summit seemed suddenly to me to be a refuge, and I had not expected to find any refuge up here. Looking at the steep, sharp ridges below us, I have the impression that to have come later would have been too late. Everything we now say to one another, we only say out of embarrassment. I don’t think anymore. As I pull the tape recorder, trancelike, from my rucksack, and switch it on wanting to record a few appropriate phrases, tears again well into my eyes. “Now we are on the summit of Everest,” I begin, “it is so cold that we cannot take photographs…” I cannot go on, I am immediately shaken with sobs. I can neither talk nor think, feeling only how this momentous experience changes everything. To reach only a few meters below the summit would have required the same amount of effort, the same anxiety and burden of sorrow, but a feeling like this, an eruption of feeling, is only possible on the summit itself.

The answers are always inside the problem, not outside.

The inside of a computer is as dumb as hell but it goes like mad!

The most remarkable discovery made by scientists is science itself. The discovery must be compared in importance with the invention of cave-painting and of writing. Like these earlier human creations, science is an attempt to control our surroundings by entering into them and understanding them from inside. And like them, science has surely made a critical step in human development which cannot be reversed. We cannot conceive a future society without science.

Thought, looked at from the inside, is not a mechanical succession of ideas, but a cry for ‘more light’.

Try to find pleasure in the speed that you’re not used to. Changing the way you do routine things allows a new person to grow inside of you.

We are made of cells. And of stars. The Universe outside of us has made the universe inside us.

We’ve all got both light and dark inside us. What matters is the part we choose to act on. That’s who we really are.

When computers (people) are networked, their power multiplies geometrically. Not only can people share all that information inside their machines, but they can reach out and instantly tap the power of other machines (people), essentially making the entire network their computer.

When I am silent, I have thunder hidden inside.

While speaking, M. Bertrand is always in motion; now he seems in combat with some outside enemy, now he outlines with a gesture of the hand the figures he studies. Plainly he sees and he is eager to paint, this is why he calls gesture to his aid. With M. Hermite, it is just the opposite; his eyes seem to shun contact with the world; it is not without, it is within he seeks the vision of truth.

You find sometimes that a Thing which seemed very Thingish inside you is quite different when it gets out into the open and has other people looking at it.

You gotta have skin.
All you really need is skin.
Skin’s the thing that if you’ve got it outside,
It helps keep your insides in.
