Experience and invention. — However far a man may go in self-knowledge, nothing however can be more incomplete than his image of the totality of drives which constitute his being. He can scarcely name even the cruder ones: their number and strength, their ebb and flood, their play and counterplay among one another, and above all the laws of their nutriment remain wholly unknown to him. This nutriment is therefore a work of chance: our daily experiences throw some prey in the way of now this, now that drive, and the drive seizes it eagerly; but the coming and going of these events as a whole stands in no rational relationship to the nutritional requirements of the totality of the drives: so that the outcome will always be twofold — the starvation and stunting of some and the overfeeding of others. Every moment of our lives sees some of the polyp-arms of our being grow and others of them wither, all according to the nutriment which the moment does or does not bear with it. Our experiences are, as already said, all in this sense means of nourishment, but the nourishment is scattered indiscriminately without distinguishing between the hungry and those already possessing a superfluity. And as a consequence of this chance nourishment of the parts, the whole, fully grown polyp will be something just as accidental as its growth has been. To express it more clearly: suppose a drive finds itself at the point at which it desires gratification — or exercise of its strength, or discharge of its strength, or the saturation of an emptiness — these are all metaphors –: it then regards every event of the day with a view to seeing how it can employ it for the attainment of its goal; whether a man is moving, or resting or angry or reading or speaking or fighting or rejoicing, the drive will in its thirst as it were taste every condition into which the man may enter, and as a rule will discover nothing for itself there and will have to wait and go on thirsting: in a little while it will grow faint, and after a couple of days or months of non-gratification it will wither away like a plant without rain. Perhaps this cruelty perpetrated by chance would be more vividly evident if all the drives were as much in earnest as is hunger, which is not content with dream food; but most of the drives, especially the so-called moral ones, do precisely this — if my supposition is allowed that the meaning and value of our dreams is precisely to compensate to some extent for the chance absence of ‘nourishment’ during the day. Why was the dream of yesterday full of tenderness and tears, that of the day before yesterday humorous and exuberant, an earlier dream adventurous and involved in a continuous gloomy searching? Why do I in this dream enjoy indescribable beauties of music, why do I in another soar and fly with the joy of an eagle up to distant mountain peaks? These inventions, which give scope and discharge to our drives to tenderness or humorousness or adventurousness or to our desire for music and mountains — and everyone will have his own more striking examples to hand — are interpretations of nervous stimuli we receive while we are asleep, very free, very arbitrary interpretations of the motions of the blood and intestines, of the pressure of the arm and the bedclothes, of the sounds made by church bells, weathercocks, night-revellers and other things of the kind. That this text, which is in general much the same on one night as on another, is commented on in such varying ways, that the inventive reasoning faculty imagines today a cause for the nervous stimuli so very different from the cause it imagined yesterday, though the stimuli are the same: the explanation of this is that today’s prompter of the reasoning faculty was different from yesterday’s — a different drive wanted to gratify itself, to be active, to exercise itself, to refresh itself, to discharge itself — today this drive was at high flood, yesterday it was a different drive that was in that condition. — Waking life does not have this freedom of interpretation possessed by the life of dreams, it is less inventive and unbridled — but do I have to add that when we are awake our drives likewise do nothing but interpret nervous stimuli and, according to their requirements, posit their ’causes’? that there is no essential difference between waking and dreaming? that when we compare very different stages of culture we even find that freedom of waking interpretation in the one is in no way inferior to the freedom exercised in the other while dreaming? that our moral judgments and evaluations too are only images and fantasies based on a physiological process unknown to us, a kind of acquired language for designating certain nervous stimuli? that all our so-called consciousness is a more or less fantastic commentary on an unknown, perhaps unknowable, but felt text? — Take some trifling experience. Suppose we were in the market place one day and we noticed someone laughing at us as we went by: this event will signify this or that to us according to whether this or that drive happens at that moment to be at its height in us — and it will be a quite different event according to the kind of person we are. One person will absorb it like a drop of rain, another will shake it from him like an insect, another will try to pick a quarrel, another will examine his clothing to see if there is anything about it that might give rise to laughter, another will be led to reflect on the nature of laughter as such, another will be glad to have involuntarily augmented the amount of cheerfulness and sunshine in the world — and in each case a drive has gratified itself, whether it be the drive to annoyance or to combativeness or to reflection or to benevolence. This drive seized the event as its prey: why precisely this one? Because, thirsty and hungry, it was lying in wait. — One day recently at eleven o’clock in the morning a man suddenly collapsed right in front of me as if struck by lightning, and all the women in the vicinity screamed aloud; I myself raised him to his feet and attended to him until he had recovered his speech — during this time not a muscle of my face moved and I felt nothing, neither fear nor sympathy, but I did what needed doing and went coolly on my way. Suppose someone had told me the day before that tomorrow at eleven o’clock in the morning a man would fall down beside me in this fashion — I would have suffered every kind of anticipatory torment, would have spent a sleepless night, and at the decisive moment instead of helping the man would perhaps have done what he did. For in the meantime all possible drives would have had time to imagine the experience and to comment on it. — What then are our experiences? Much more that which we put into them than that which they already contain! Or must we go so far as to say: in themselves they contain nothing? To experience is to invent? — (Nietzsche, Daybreak, 119)
