Distilling is beautiful. First of all, because it is a slow, philosophic and silent occupation, which keeps you busy but gives you time to think of other things, somewhat like riding a bike. Then, because it involves a metamorphosis from liquid to vapor (invisible), and from this once again to liquid; but in this double journey, up and down, purity is attained, an ambiguous and fascinating condition, which starts with chemistry and goes very far. And finally, when you set about distilling, you acquire the consciousness of repeating a ritual consecrated by the centuries, almost a religious act, in which from imperfect material you obtain the essence, the usia, the spirit, and in the first place alcohol, which gladdens the spirit and warms the heart.


After two months I had about forty analyses: the plants with a higher phosphorus content were sage, celandine, and parsley.


It seems almost as if to be is to quarrel, or at least to differ, to be in contrast with something else. If so, whoever does not put up a fight has no identity; whoever is not selfish has no self. Nothing unites a community so much as common cause against an external enemy, yet, in the same moment, that enemy becomes the essential support of social unity. Therefore larger societies require larger enemies, bringing us in due course to the perilous point of our present situation, where the world is virtually divided into two huge camps. But if high officers on both sides have any intelligence at all, they make a secret agreement to contain the conflict: to call each other the worst names, but to refrain from dropping bombs. Or, if they insist that there must be some fighting to keep armies in trim, they restrict it to local conflicts in 'unimportant' countries. Voltaire should have said that if the Devil did not exist, it would be necessary to invent him. Nevertheless, the more it becomes clear that to be is to quarrel and to pursue self-interest, the more you are compelled to recognize your need for enemies to support you. In the same way, the more resolutely you plumb the question 'Who or what am I?'—the more unavoidable is the realization that you are nothing at all apart from everything else. Yet again, the more you strive for some kind of perfection or mastery—in morals, in art or in spirituality—the more you see that you are playing a rarified and lofty form of the old ego-game, and that your attainment of any height is apparent to yourself and to others only by contrast with someone else's depth or failure. This understanding is at first paralyzing. You are in a trap—in the worst of all double-binds—seeing that any direction you may take will imply, and so evoke, its opposite. Decide to be a Christ, and there will be a Judas to betray you and a mob to crucify you. Decide to be a devil, and men will unite against you in the closest brotherly love. Your first reaction may be simply, 'To hell with it!' The only course may seem to be to forget the whole effort and become absorbed in trivialities, or to check out of the game by suicide or psychosis, and spend the rest of your days blabbering in an asylum. But there is another possibility. Instead of checking out, let us ask what the trap means. What is implied in finding yourself paralyzed, unable to escape from a game in which all the rules are double-binds and all moves self-defeating? Surely this is a deep and intense experience of the same double-bind that was placed upon you in infancy, when the community told you that you must be free, responsible, and loving, and when you were helplessly defined as an independent agent. The sense of paralysis is therefore the dawning realization that this is nonsense and that your independent ego is a fiction. It simply isn't there, either to do anything or to be pushed around by external forces, to change things or to submit to change. The sense of 'I,' which should have been identified with the whole universe of your experience, was instead cut off and isolated as a detached observer of that universe. In the preceding chapter we saw that this unity of organism and environment is a physical fact. But when you know for sure that your separate ego is a fiction, you actually feel yourself as the whole process and pattern of life. Experience and experiencer become one experiencing, known and knower one knowing. Each organism experiences this from a different standpoint and in a different way, for each organism is the universe experiencing itself in endless variety. One need not, then, fall into the trap which this experience holds for believers in an external, all-powerful God—the temptation to feel 'I am God' in that sense, and to expect to be worshipped and obeyed by all other organisms. Remember, above all, that an experience of this kind cannot be forced or made to happen by any act of your fictitious 'will,' except insofar as repeated efforts to be one-up on the universe may eventually reveal their futility. Don't try to get rid of the ego-sensation. Take it, so long as it lasts, as a feature or play of the total process—like a cloud or wave, or like feeling warm or cold, or anything else that happens of itself. Getting rid of one's ego is the last resort of invincible egoism! It simply confirms and strengthens the reality of the feeling. But when this feeling of separateness is approached and accepted like any other sensation, it evaporates like the mirage that it is. This is why I am not overly enthusiastic about the various 'spiritual exercises' in meditation or yoga which some consider essential for release from the ego. For when practiced in order to 'get' some kind of spiritual illumination or awakening, they strengthen the fallacy that the ego can toss itself away by a tug at its own bootstraps. But there is nothing wrong with meditating just to meditate, in the same way that you listen to music just for the music. If you go to concerts to 'get culture' or to improve your mind, you will sit there as deaf as a doorpost. If, then, you ask me how to get beyond the ego-feeling, I shall ask you why you want to get there. If you give me the honest answer, which is that your ego will feel better in the 'higher spiritual status' of self-transcendence, you will thus realize that you—as ego—are a fake. You will feel like an onion: skin after skin, subterfuge after subterfuge, is pulled off to find no kernel at the center. Which is the whole point: to find out that the ego is indeed a fake—a wall of defense around a wall of defense ... around nothing. You can't even want to get rid of it, nor yet want to want to. Understanding this, you will see that the ego is exactly what it pretends it isn't. Far from being the free center of personality, it is an automatic mechanism implanted since childhood by social authority, with—perhaps—a touch of heredity thrown in. This may give you the temporary feeling of being a zombie or a puppet dancing irresponsibly on strings that lead away to unknown forces. At this point, the ego may reassert itself with the insidious 'I-can't-help-myself' play in which the ego splits itself in two and pretends that it is its own victim. 'See, I'm only a bundle of conditioned reflexes, so you mustn't get angry with me for acting just as I feel.' (To which the answer could be, 'Well, we're just zombies too, so you shouldn't complain if we get angry.') But who is it that mustn't get angry or shouldn't complain, as if there were still some choice in the matter? The ego is still surviving as the 'I' which must passively endure the automatic behavior of 'myself' and others—again, as if there were some choice which the witnessing self can make between putting up with things and attacking them violently. What has happened is that the frustrated ego has withdrawn into its last stronghold of independence, retaining its identity as a mere watcher, or sufferer, of all that goes on. Here it pities itself or consoles itself as a puppet of fate. But if this is seen as yet another subterfuge, we are close to the final showdown. A line of separation is now drawn between everything that happens to me, including my own feelings, on the one side, and on the other, I myself as the conscious witness. Isn't it easy to see that this line is imaginary, and that it, and the witness behind it, are the same old faking process automatically learned in childhood? The same old cleft between the knower and the known? The same old split between the organism/environment and the organism's feedback, or self-conscious mechanism? If, then, there is no choice in what happens to me, on one side of the line, there is equally no choice on the other, on the witnessing side, as to whether I should accept what happens or reject it. I accept, I reject, I witness just as automatically as things happen or as my emotions reflect my physiological chemistry. Yet in this moment when one seems about to become a really total zombie, the whole thing blows up. For there is not fate unless there is someone or something to be fated. There is no trap without someone to be caught. There is, indeed, no compulsion unless there is also freedom of choice, for the sensation of behaving involuntarily is known only by contrast with that of behaving voluntarily. Thus when the line between myself and what happens to me is dissolved and there is no stronghold left for an ego even as a passive witness, I find myself not in a world but as a world which is neither compulsive nor capricious. What happens is neither automatic nor arbitrary: it just happens, and all happenings are mutually interdependent in a way that seems unbelievably harmonious.

Few parts of the Lord's Prayer have given more trouble to the praying Christian and more scope for the exegete than the verse: \r\n\r\n>And lead us not into temptation, but deliver us from evil (Matt 6:13) \r\n\r\nThe Greek word for 'temptation', peirasmos, came in for special attention at the time of the decipherment of the Dead Sea Scrolls. It was realized correctly by scholars that behind this New Testament phrase lay the Semitic word for a place for 'testing' metals, that is, the refiner's crucible. The Essenes in the Scrolls talk of the 'time of testing that is coming' using the technical word. So, here, in the Prayer, the word-jugglers have taken its Aramaic equivalent, kur bukhana', 'crucible of testing', out of LI-KUR-BA (LA)G-ANTA, the mushroom name. The resultant phrase is particularly interesting because it is almost exactly the Aramaic name of the fungus as it has come down in literature, khurbakhna' or khurbekhana' (Arabic kharbaq), attached, like so many mushroom words, to the plant Hellebore. \r\n\r\nTaking the sacred fungus, or, in New Testament parlance, 'eating the body' of the Christ, must have been a very real peirasmos, 'trial', of the body and spirit. It would have seemed no accident to the cultic celebrant that the name of the mushroom and the phrase for 'fiery furnace of testing' appeared the same. The customary translations of the powerful concept as 'temptation' is almost ridiculous, recalling youthful experiences in the jam-cupboard or behind the woodshed with the girl next door. Well might the writer of Corinthians issue the warning: \r\n\r\n>Whoever, therefore, eats the bread or drinks the cup of the Lord unworthily will be guilty of profaning the body and blood of the Lord. Let a man examine himself, and so eat of the bread and drink of the cup. For anyone who eats and drinks without critically treating his body, eats and drinks a 'crisis' upon himself. That is why many of you are weak and ill, and some have died... (1 Cor 11:27-30). \r\n\r\nThe Amanita muscaria is, after all, a poisonous fungus. Whist not the most dangerous, its drugs have a serious affect on the nervous system, and taken regularly over a long period would in the end kill the addict. Among its drugs so far isolated are Muscarine, Atropine, and Bufotenin. The first causes vomiting and diarrhoea, and stimulates the parasympathetic nervous system so that the partaker is capable of great feats of muscular exertion and endurance. The stories which came down of the fantastic strength exhibited by cultic heroes, however mythical the events described, have probably that element of real fact. So, too, the idea that the Maenads in their wild raving through the conifer forests were capable of tearing animals limb from limb, was not entirely devoid of truth. \r\n\r\nAtropine first stimulates the nervous system and then paralyzes it. It is this poison that is primarily responsible for the hallucinatory effects of the sacred fungus, but also for the muscular convulsions that must have seemed to bystanders like the demons within, wresting with the newly imbibed power of the god. \r\n\r\nBufotenin, a secretion otherwise found in the sweat glands of the African toad, lowers the pulse rate and temperature. As a result, the mushroom eater has the strange sensation of feeling his skin hot and cold simultaneously: hot in some places, cold in others. He finds himself hypersensitive to touch, light, and sound. The day following his 'trip' he will find all smells seem foul and a bad taste persists in his mouth. He feels an urgent need to urinate but is unable to do so.

It is no good taking the right number of atoms and shaking them together with some external energy till they happen to fall into the right pattern, and out drops Adam! You may make a molecule consisting of a few dozen atoms like that, but a man consists of over a thousand million million million million atoms. To try to make a man, you would have to work at your biochemical cocktail-shaker for a period so long that the entire age of the universe would seem like an eye-blink, and even then you would not succeed. This is where Darwin's theory, in its most general form, comes to the rescue. Darwin's theory takes over from where the story of the slow building up of molecules leaves off.

Q. How do these hydrogens connect with man? A. For instance, hydrogen 768 represents all the food we eat; the air we breathe is hydrogen 192, and our impressions can be 48, 24, 12 and even 6. We have an enormous range of impressions, but we have no choice of air or food. We cannot inhale, for instance, hydrogen 96, for it is fire, incandescent gases. We cannot eat H 384, for it is water, and we cannot live on water. You will see that this Table answers all our requirements; it enables us to speak of all the matters in the human machine and to see their interrelation; and it makes it possible to connect man with the universe, because we can know from which level each matter comes. This Table of hydrogens shows not only the density of each of thembut also the place of origin of these different layers of matter which are under different laws, as it was explained. Hydrogens which come from planes under a very small number of laws, near the Will of the Absolute, have an enormous power and enormous potential energy. Thus we have a scale of twelve densities on which can be placed all matter known to or conceivable by man. For the lower densities we may find examples both in man and in the world around him. Up to the level of H 96 or even 48, these may be studied physically by chemistry, biology and other sciences. Above H 48 we can only study psychological effects of their presence or absence— knowing the level of hydrogens with which different centres work. Still higher hydrogens are only potential in man or exist in such small quantities that they are impossible to study. The study of these higher hydrogens in the surrounding world is also beyond the powers of perception of man No. 1, 2 and 3

Mother Nature 'is just chemistry, biology, and physics,' Watson likes to say.  'Everything she does is just the sum of those three things.  She's completely amoral.  She doesn't care about poetry or art or whether you go to church.  You can't negotiate with her, and you can't spin her and you can't evade her rules.  All you can do is fit in as a species.  And when a species doesn't learn to fit in with Mother Nature, it gets kicked out.'  It's that simple, says Watson, and that's why 'every day you look in the mirror now, you're seeing an endangered species.

Although in general Gary applauded the modern trend toward individual self-management of retirement funds and long-distance calling plans and private-schooling options, he was less than thrilled to be given responsibility for his own personal brain chemistry, especially when certain people in his life, notably his father, refused to take any such responsibility. But Gary was nothing if not conscientious. As he entered the darkroom, he estimated that his levels of Neurofactor 3 (i. e., serotonin: a very, very important factor) were posting seven-day or even thirty-day highs, that his Factor 2 and Factor 7 levels were likewise outperforming expectations, and that his Factor 1 had rebounded from an early-morning slump related to the glass of Armagnac he’d drunk at bedtime. He had a spring in his step, an agreeable awareness of his above-average height and his late-summer suntan. His resentment of his wife, Caroline, was moderate and well contained. Declines led advances in key indices of paranoia (e. g., his persistent suspicion that Caroline and his two older sons were mocking him), and his seasonally adjusted assessment of life’s futility and brevity was consistent with the overall robustness of his mental economy. He was not the least bit clinically depressed.


What a startling doctrine [Behaviorism is]! But the really surpising thing is that, starting off almost as a flying whim, it grew into a movement that occupied center stage in psychology from about 1920 to 1960. The external reasons for the sustained triumph of such a peculiar position are both fascinating and complex. Psychology at the time was trying to wriggle out of philosophy into a separate academic discipline and used behaviorism to do so. The immediate adversary of behaviorism, Titchenerian introspectionism, was a pale and effete opponent, based as it was on a false anaology between consciousness and chemistry. The toppled idealism of World War I created a revolutionary age demanding new philosophies. The intriguing succeses of physics and general technology presented both a model and a means that seemed more compatible with behaviorism. The world was weary and wary of subjective thought and longed for objective fact. Anf in America objective fact was pragmatic fact. Behaviorism provided this in psychology. It allowed a new generation to sweep aside with one impatient gesture all the worn-out complexities of the problem of consciousness and its origin. We would turn over a new leaf. We would make a fresh start.\n\n And the fresh start was a success in one laboratory after another. But the single inherent reason for its success was not its truth, but its program. And what a truly vigorous and exciting program of research it was! with its gleaming stainless-steel promise of reducting all conduct to a handful of reflexes and conditional responses developed from them, of generalizing the spinal reflex terminology of stimulus and response and reinforcement to the puzzles of headed behavior and so seeming to solve them, of r unning rats through miles and miles of mazes into more fascinating mazes of objective theorems, and its pledge, its solemn pledge to reduce thought to muscle twitches and peronality to the woes of Little Albert. In all this there was a heady excitement that is difficult to relate at this remove. Complexity would be made simple, darkness would be made light, and philosophy would be a thing of the past.

The sexual potency, drive, and power of a human being are to some extent determined by his inheritance and his chemistry, but they seem to be even more strongly influenced by the script decisions he makes in early childhood, and by the parental programming which brings about those decisions.
