Philosophers, says Comte,* have "in these latter days imagined themselves able to distinguish, by a very singular subtlety, two sorts of observation of equal importance, one external, the other internal, the latter being solely destined for the study of intellectual phenomena. ... I limit myself to pointing out the principal consideration which proves clearly that this pretended direct contemplation of the mind by itself is a pure illusion. . . . It is in fact evident that, by an invincible neccessity, the human mind can observe directly all phenomena except its own proper states. For by whom shall the observation of these be made ? It is conceivable that a man might observe himself with respect to the passions that animate him, for the anatomical organs of passion are distinct from those whose function is observation. Though we have all made such observations on ourselves, they can never have much scientific value, and the best mode of knowing the passions will always be that of ob- serving them from without ; for every strong state of passion ... is necessarily incompatible with the state of observation. But, as for observing in the same way intellectual phenomena at the time of their actual presence, that is a manifest impossibility. The thinker cannot divide himself into two, of whom one reasons whilst the other observes him reason. The organ observed and the organ observing being, in this case, identical, how could observation take place ? This pretended psychological method is then radically null and void. On the one hand, they advise you to isolate yourself, as far as possible, from every external sensation, especially every intellectual work, — for if you were to busy yourself even with the simplest calculation, what would become of internal observation ? — on the other hand, after having with the utmost care attained this state of intellectual slumber, you must begin to contemplate the operations going on in your mind, when nothing there takes place ! Our descendants will doubtless see such pretensions some day ridiculed upon the stage. The results of so strange a proced- ure harmonize entirely with its principle. For all the two thousand years during which metaphysicians have thus cultivated psychology, they are not agreed about one intelligible and established proposition. ' Internal observation ' gives almost as many divergent results as there are individuals who think they practise it." Comte hardly could have known anything of the English, and nothing of the German, empirical psychology. The ' results ' which he had in mind when writing were probably
