and, by implication, positivismâhave become events of considerable historical consequence, since, with the beginning of our century, they have ceased to be the exclusive concern of an intellectual elite and instead are not so much the concern as the common unexamined assumption of nearly everybody. With this political aspect of the matter we are not concerned here. In our context, it may even be better to leave the issue, which actually is one of political authority, outside our considerations, and to insist, rather, on the simple fact that, however seriously our ways of thinking may be involved in this crisis, our
ability
to think is not at stake; we are what men always have beenâthinking beings. By this I mean no more than that men have an inclination, perhaps a need, to think beyond the limitations of knowledge, to do more with this ability than use it as an instrument for knowing and doing. To talk about nihilism in this context is perhaps just unwillingness to part company with concepts and thought-trains that actually died quite some time ago, though their demise has been publicly acknowledged only recently. If only, one would like to imagine, we could do in this situation what the modem age did in its early stage, that is, treat each and every subject "as though no one had touched the matter before me" (as Descartes proposes in his introductory remarks to "
Les Passions de l'âme")!
This has become impossible, partly because of our enormously enlarged historical consciousness, but primarily because the only record we possess of what thinking as an activity meant to those who had chosen it as a way of life is what we would call today the "metaphysical fallacies." None of the systems, none of the doctrines transmitted to us by the great thinkers may be convincing or even plausible to modern readers; but none of them, I shall try to argue here, is arbitrary and none can be simply dismissed as sheer nonsense. On the contrary, the metaphysical fallacies contain the only clues we have to what thinking means to those Who engage in itâsomething of great importance today and about which, oddly enough, there exist few direct utterances.
Hence, the possible advantage of our situation following the demise of metaphysics and philosophy would be twofold. It would permit us to look on the past with new eyes, unburdened and unguided by any traditions, and thus to dispose of a tremendous wealth of raw experiences without being bound by any prescriptions as to how to deal with these treasures. "
Notre héritage n'est précédé d'aucun testament
" ("Our inheritance comes to us by no will-and-testament"). 19 The advantage would be even greater had it not been accompanied, almost inevitably, by a growing inability to move, on no matter what level, in the realm of the invisible; or, to put it another way, had it not been accompanied by the disrepute into which everything that is not visible, tangible, palpable has fallen, so that we are in danger of losing the past itself together with our traditions.
For even though there has never been much consensus about the subject matter of metaphysics, at least one point has been taken for granted: that these disciplinesâwhether you called them metaphysics or philosophyâdealt with matters that were not given to sense-perception and that their understanding transcended common-sense reasoning, which springs from sense experience and can be validated by empirical tests and means. From Parmenides till philosophy's end, all thinkers were agreed that, in order to deal with such matters, man had to detach his mind from the senses by detaching it both from the world as given by them and from the sensationsâor passionsâaroused by sense-objects. The philosopher, to the extent that he is a philosopher and not (what of course he also is) "a man like you and me," withdraws from the world of appearances, and the region he then moves in has always, since philosophy's
