Seite 37 - ... in 1800. Bichat's views seem so relevant to the present discussion that it may be appropriate to conclude with their quotation: "The action of the mind on each feeling of pain or pleasure, arising from a sensation, consists in a comparison between that sensation and those which have preceded it. The greater the difference between the actual and past impressions, the more ardent will be the feeling. That sensation would affect us most which we had never experienced before. "It follows, therefore,...

Seite 37 - ... frequency of their repetition, because the comparison becomes less sensible between their past and actual state. Every time that we see an object, hear a sound, or taste a dish, we find less difference between what we experience and what we have experienced. "The nature of pleasure and of pain is thus to destroy themselves, to cease to exist, because they have existed. The art of prolonging the duration of our enjoyments consists in varying their causes.

He says : " Strict observation proves to us that the parts subservient to the internal functions are constantly affected by them, and are ever determined according to the state in which they may be. The effect of every kind of passion is to produce some change, some alteration in organic life. Anger accelerates the circulation, and increases, often in an incommensurable proportion, the effort of the heart ; it is on the force,...

But again, says he, " Perhaps the internal organs do not act upon the voluntary muscles by the intermediate excitement of the brain, but by direct nervous communications; how they act' is of no consequence, * * what is most essential, is the fact itself; what is evidently in support of it, is, on the one part, the affection of an internal organ by the passions; on the other part the determinate motion to this...
Seite 65 - ... which bear the character of vitality, have been alternately the common base on which have rested all physiological explanations. These bases have been successively overturned, and among their ruins the facts alone remain which a rigorous experience of sensibility and mobility furnish. Such, indeed, are the narrow limits of the human understanding, that the knowledge of first causes is almost always denied to it. The thick veil which covers them, envelops in its innumerable folds whoever attempts...
Seite 46 - Respiration has a no less immediate dependence on the passions ; those suffocations, that oppression, the sudden effect of profound grief, do they not indicate some remarkable change, some sudden alteration in the lungs ? In the long catalogue of chronic diseases, or of acute affections, the sad attribute of the pulmonary system, are we not often obliged to trace the different passions of the patient to discover the principle of his disease ?
