Esse est percipi

It is indeed an Opinion strangely prevailing amongst Men, that Houses, Mountains, Rivers, and in a word all sensible Objects have an Existence Natural or Real, distinct from their being perceived by the Understanding. But with how great an Assurance and Acquiescence soever this Principle may be entertained in the World; yet whoever shall find in his Heart to call it in Question, may, if I mistake not, perceive it to involve a manifest Contradiction. For what are the forementioned Objects but the things we perceive by Sense, and what do we perceive besides our own Ideas or Sensations; and is it not plainly repugnant that any one of these or any Combination of them should exist unperceived?

Some Truths there are so near and obvious to the Mind, that a Man need only open his Eyes to see them. Such I take this Important one to be, to wit, that all the Choir of Heaven and Furniture of the Earth, in a word all those Bodies which compose the mighty Frame of the World, have not any Subsistence without a Mind.

Unnum

I have read many writings both of heathen philosophers and inspired prophets, ancient and modern, and have sought earnestly to discover what is the best and highest quality whereby man may approach most nearly to union with God, and whereby he may most resemble the ideal of himself which existed in God, before God created men.

And after having thoroughly searched these writings as far as my reason may penetrate, I find no higher quality than sanctification or separation from all creatures. Therefore said our Lord to Martha, “One thing is necessary,” as if to say, “whoso wishes to be untroubled and content, must have one thing, that is sanctification.”

Meister Eckhart – Sanctification

Luke 10,38-42
38 As Jesus and his disciples were on their way, he came to a village where a woman named Martha opened her home to him. 39 She had a sister called Mary, who sat at the Lord’s feet listening to what he said. 40 But Martha was distracted by all the preparations that had to be made. She came to him and asked, “Lord, don’t you care that my sister has left me to do the work by myself? Tell her to help me!” 41 “Martha, Martha,” the Lord answered, “you are worried and upset about many things, 42 but few things are needed—or indeed only one.

Die Welt ist meine Vorstellung

The world is my idea. This is a truth which holds good for everything that lives and knows, though man alone can bring it into reflective and abstract consciousness. If he really does this, he has attained to philosophical wisdom. It then becomes clear and certain to him that what he knows is not a sun and an earth, but only an eye that sees a sun, a hand that feels an earth; that the world which surrounds him is there only as idea, i.e., only in relation to something else, the consciousness, which is himself.

Escape from Freedom

The spiritual relatedness to the world can assume many forms; the monk in his cell who believes in God and the political prisoner kept in isolation who feels one with his fellow-fighters are not alone morally. The kind of relatedness to the world may be noble or trivial, but even being related to the basest kind of pattern is immensely preferable to being alone.

Religion and nationalism, as well as any custom and any belief however absurd and degrading, if it only connects the individual with others, are refuges from what man most dreads: isolation.

Erich Fromm – The Fear of Freedom

Solipsism of Zen

In this whole world everyone searches for happiness outside, but nobody understands their true self inside. Everybody says, “I” — “I want this, I am like that…” But nobody understands this “I.” Before you were born, where did your I come from? When you die, where will your I go? If you sincerely ask, “what am I?” sooner or later you will run into a wall where all thinking is cut off. We call this “don’t know.” Zen is keeping this “Don’t Know” mind always and everywhere.

Butterfly Dream

Once upon a time, Zhuang Zhou dreamed he was a butterfly, a butterfly flitting about happily enjoying himself. He did not know that he was Zhou. Suddenly he awoke, and was palpably Zhou. He did not know whether he was Zhou, who had dreamed of being a butterfly, or a butterfly dreaming that he was Zhou.

De omnibus dubitandum

Some years ago I was struck by how many false things I had believed, and by how doubtful was the structure of beliefs that I had based on them. I realized that if I wanted to establish anything in the sciences that was stable and likely to last, I needed – just once in my life – to demolish everything completely and start again from the foundations. It looked like an enormous task, and I decided to wait until I was old enough to be sure that there was nothing to be gained from putting it off any longer. I have now delayed it for so long that I have no excuse for going on planning to do it rather than getting to work. So today I have set all my worries aside and arranged for myself a clear stretch of free time. I am here quite alone, and at last I will devote myself, sincerely and without holding back, to demolishing my opinions.

Whatever I have accepted until now as most true has come to me through my senses. But occasionally I have found that they have deceived me, and it is unwise to trust completely those who have deceived us even once. Yet although the senses sometimes deceive us about objects that are very small or distant, that does not apply to my belief that I am here, sitting by the fire, wearing a winter dressing-gown, holding this piece of paper in my hands, and so on. It seems to be quite impossible to doubt beliefs like these, which come from the senses. Another example: how can I doubt that these hands or this whole body are mine? To doubt such things I would have to liken myself to brain-damaged madmen who are convinced they are kings when really they are paupers, or say they are dressed in purple when they are naked, or that they are pumpkins, or made of glass. Such people are insane, and I would be thought equally mad if I modeled myself on them.

As if I were not a man who sleeps at night and often has all the same experiences while asleep as madmen do when awake – indeed sometimes even more improbable ones. Often in my dreams I am convinced of just such familiar events – that I am sitting by the fire in my dressing-gown – when in fact I am lying undressed in bed! Yet right now my eyes are certainly wide open when I look at this piece of paper; I shake my head and it isn’t asleep; when I rub one hand against the other, I do it deliberately and know what I am doing. This wouldn’t all happen with such clarity to someone asleep. Indeed! As if I didn’t remember other occasions when I have been tricked by exactly similar thoughts while asleep! As I think about this more carefully, I realize that there is never any reliable way of distinguishing being awake from being asleep.

Habitual Beliefs of Age or Nation

The man who has no tincture of philosophy goes through life imprisoned in the prejudices derived from common sense, from the habitual beliefs of his age or his nation, and from convictions which have grown up in his mind without the co-operation or consent of his deliberate reason. To such a man the world tends to become definite, finite, obvious; common objects rouse no questions, and unfamiliar possibilities are contemptuously rejected. As soon as we begin to philosophize, on the contrary, we find, as we saw in our opening chapters, that even the most everyday things lead to problems to which only very incomplete answers can be given.

Bertrand Russell – The Problems of Philosophy

La vida es sueño

In one sense it must be admitted that we can never prove the existence of things other than ourselves and our experiences. No logical absurdity results from the hypothesis that the world consists of myself and my thoughts and feelings and sensations, and that everything else is mere fancy. There is no logical impossibility in the supposition that the whole of life is a dream, in which we ourselves create all the objects that come before us.

On Truth and Lies

To begin with, a nerve stimulus is transferred into an image: first metaphor. The image, in turn, is imitated in a sound: second metaphor. And each time there is a complete overleaping of one sphere, right into the middle of an entirely new and different one.

One can imagine a man who is totally deaf and has never had a sensation of sound and music. Perhaps such a person will gaze with astonishment at Chladni’s sound figures; perhaps he will discover their causes in the vibrations of the string and will now swear that he must know what men mean by “sound.”

It is this way with all of us concerning language; we believe that we know something about the things themselves when we speak of trees, colors, snow, and flowers; and yet we possess nothing but metaphors for things–metaphors which correspond in no way to the original entities.
