Werner Heisenberg

Not only is the Universe stranger than we think, it is stranger than we can think.

The first gulp from the glass of natural sciences will turn you into an atheist, but at the bottom of the glass God is waiting for you.

What we observe is not nature itself, but nature exposed to our method of questioning.

There are things that are so serious that you can only joke about them.

The reality we can put into words is never reality itself.

An expert is someone who knows some of the worst mistakes that can be made in his subject, and how to avoid them.

The existing scientific concepts cover always only a very limited part of reality, and the other part that has not yet been understood is infinite. Whenever we proceed from the known into the unknown we may hope to understand, but we may have to learn at the same time a new meaning of the word ‘understanding’.

…science started from the belief — or should one say, from the illusion? — that we could describe the world, or least parts of the world, without any reference to ourselves.

Revere those things beyond science which really matter and about which it is so difficult to speak.

The positivists have a simple solution: the world must be divided into that which we can say clearly and the rest, which we had better pass over in silence. But can anyone conceive of a more pointless philosophy, seeing that we can say clearly amounts to next to nothing? If we omitted all that is unclear, we would probably be left completely uninteresting and trivial tautologies.

Rabindranath Tagore

A mind all logic is like a knife all blade. It makes the hand bleed that uses it. 

Beauty is truth’s smile when she beholds her own face in a perfect mirror. 

Bigotry tries to keep truth safe in its hand with a grip that kills it.

By plucking her petals, you do not gather the beauty of the flower.

Clouds come floating into my life, no longer to carry rain or usher storm, but to add color to my sunset sky.

Death is not extinguishing the light; it is only putting out the lamp because the dawn has come.

Depth of friendship does not depend on length of acquaintance.

Do not say, ‘It is morning,’ and dismiss it with a name of yesterday. See it for the first time as a newborn child that has no name.

Don’t limit a child to your own learning, for he was born in another time.

Emancipation from the bondage of the soil is no freedom for the tree.

Every child comes with the message that God is not yet discouraged of man.

Every difficulty slurred over will be a ghost to disturb your repose later on.

Everything comes to us that belong to us if we create the capacity to receive it.

Facts are many, but the truth is one.

Faith is the bird that feels the light when the dawn is still dark.

From the solemn gloom of the temple children run out to sit in the dust, God watches them play and forgets the priest.  

He who is too busy doing well finds no time to be good.

I have become my own version of an optimist. If I can’t make it through one door, I’ll go through another door – or I’ll make a door. Something terrific will come no matter how dark the present.

I slept and dreamt that life was joy. I awoke and saw that life was service. I acted and behold, service was joy.

If you shut the door to all errors, truth will be shut out.

In Art, man reveals himself and not his objects.

Let us not pray to be sheltered from dangers but to be fearless when facing them.

Let your life lightly dance on the edges of Time like dew on the tip of a leaf.

Life is given to us; we earn it by giving it.

Love does not claim possession, but gives freedom.

Love is an endless mystery, for it has nothing else to explain it.

Love is not a mere impulse; it must contain truth, which is law.

Love is the only reality and it is not a mere sentiment. It is the ultimate truth that lies at the heart of creation.

Music fills the infinite between two souls.

The burden of the self is lightened with I laugh at myself.

The butterfly counts not months but moments, and has time enough.

The flower which is single need not envy the thorns that are numerous.

The highest education is that which does not merely give us information but makes our life in harmony with all existence.

The water in a vessel is sparkling; the water in the sea is dark. The small truth has words which are clear; the great truth has great silence.

Those who own much have much to fear.

To be outspoken is easy when you do not wait to speak the complete truth.

Trees are Earth’s endless effort to speak to the listening heaven.

We come nearest to the great when we are great in humility.

We gain freedom when we have paid the full price.

We live in the world when we love it.

Your idol is shattered in the dust to prove that God’s dust is greater than your idol.

Amartya K. Sen

The power to do good goes almost always with the possibility to do the opposite…

If a theory of justice is to guide reasoned choice of policies, strategies or institutions, then the identification of fully just social arrangements is neither necessary nor sufficient.

The identity of an individual is essentially a function of her choices, rather than the discovery of an immutable attribute.

Rainer Maria Rilke

Be patient toward all that is unsolved in your heart and try to love the questions themselves, like locked rooms and like books that are now written in a very foreign tongue. Do not now seek the answers, which cannot be given you because you would not be able to live them. And the point is, to live everything. Live the questions now. Perhaps you will then gradually, without noticing it, live along some distant day into the answer.

Perhaps all the dragons in our lives are princesses who are only waiting to see us act, just once, with beauty and courage. Perhaps everything that frightens us is, in its deepest essence, something helpless that wants our love.

Love consists of this: two solitudes that meet, protect and greet each other….We need, in love, to practice only this: letting each other go. For holding on comes easily; we do not need to learn it.

Oscar Wilde

Laughter is not at all a bad beginning for a friendship, and it is far the best ending for one.

Our ambition should be to rule ourselves, the true kingdom for each one of us; and true progress is to know more, and be more, and to do more.
