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.
We will have false conceptions of the indestructibility of our true nature by death, so long as we do not make up our minds to study it primarily in the brutes, but claim for ourselves alone a class apart from them, under the boastful name of immortality. But it is this pretension alone, and the narrowness of view from which it proceeds, on account of which most men struggle so obstinately against the recognition of the obvious truth that we are essentially, and in the chief respect, the same as the brutes; nay, that they recoil at every hint of our relationship with these. But it is this denial of the truth which more than anything else closes against them the path to real knowledge of the indestructibility of our nature. For if we seek anything upon a wrong path, we have just on that account forsaken the right path, and upon the path we follow we will never attain to anything in the end but late disillusion. Up, then, follow the truth, not according to preconceived notions, but as nature leads! First of all, learn to recognise in the aspect of every young animal the existence of the species that never grows old, which, as a reflection of its eternal youth, imparts to every individual a temporary youth, and lets it come forth as new and fresh as if the world were of to-day. Let one ask himself honestly whether the swallow of this year's spring is absolutely a different one from the swallow of the first spring
