_(Stulta, et prolixas non admittentia curas_ _Pectora: qui sperant, existere posse, quod ante_ _Non fuit, aut ullam rem pessum protinus ire_;— _Non animo prudens homo quod præsentiat ullus_, _Dum vivunt (namque hoc vitaï nomine signant)_, _Sunt, et fortuna tum conflictantur utraque_: _Ante ortum nihil est homo, nec post funera quidquam.)_ The very remarkable and, in its place, astonishing passage in Diderot’s “_Jacques le fataliste_,” deserves not less to be mentioned here: “_Un château immense, au frontispice duquel on lisait: __‹ __Je n’appartiens à personne, et j’appartiens à tout le monde: vous y étiez avant que d’y entrer, vous y serez encore, quand vous en sortirez__ ›_.” Certainly in the sense in which, when he is begotten, the man arises out of nothing, he becomes nothing through death. But really to learn to know this “nothing” would be very interesting; for it only requires moderate acuteness to see that this empirical nothing is by no means absolute, _i.e._, such as would in every sense be nothing. We are already led to this insight by the observation that all qualities of the parents recur in the children, thus have overcome death. Of this, however, I will speak in a special chapter. There is no greater contrast than that between the ceaseless flight of time, which carries its whole content with it, and the rigid immobility of what is actually present, which at all times is one and the same. And if from this point of view we watch in a purely objective manner the immediate events of life, the _Nunc stans_ becomes clear and visible to us in the centre of the wheel of time. To the eye of a being of incomparably longer life, which at _one_ glance comprehended the human race in its whole duration, the constant alternation of birth and death would present itself as a continuous vibration, and accordingly it would not occur to it at all to see in this an ever new arising out of nothing and passing into nothing; but just as to our sight the quickly revolving spark appears as a continuous circle, the rapidly vibrating spring as a permanent triangle, the vibrating cord as a spindle, so to this eye the species would appear as that which has being and permanence, death and life as vibrations.
