[79] Observe, in passing, that what gives every positive system of religion its great strength, the point of contact through which it takes possession of the soul, is entirely its ethical side. Not, however, the ethical side directly as such, but as it appears firmly united and interwoven with the element of mythical dogma which is present in every system of religion, and as intelligible only by means of this. So much is this the case, that although the ethical significance of action cannot be explained in accordance with the principle of sufficient reason, yet since every mythus follows this principle, believers regard the ethical significance of action as quite inseparable, and indeed as absolutely identical, and regard every attack upon the mythus as an attack upon right and virtue. This goes so far that among monotheistic nations atheism or godlessness has become synonymous with the absence of all morality. To the priests such confusions of conceptions are welcome, and only in consequence of them could that horrible monstrosity fanaticism arise and govern, not merely single individuals who happen to be specially perverse and bad, but whole nations, and finally embody itself in the Western world as the Inquisition (to the honour of mankind be it said that this only happened once in their history), which, according to the latest and most authentic accounts, in Madrid alone (in the rest of Spain there were many more such ecclesiastical dens of murderers) in 300 years put 300,000 human beings to a painful death at the stake on theological grounds—a fact of which every zealot ought to be reminded whenever he begins to make himself heard.
