terrestrial magnetism; and that this magnetism, again, is the cause of
the _aurora borealis_, these would be truths externally of great, but
internally of little, significance. On the other hand, examples
of internal significance are furnished by all great and true
philosophical systems; by the catastrophe of every good tragedy; nay,
even by the observation of human conduct in the extreme manifestations
of its morality and immorality, of its good and its evil character.
For all these are expressions of that reality which takes outward
shape as the world, and which, in the highest stages of its
objectivation, proclaims its innermost nature.

To say that the world has only a physical and not a moral significance
is the greatest and most pernicious of all errors, the fundamental
blunder, the real perversity of mind and temper; and, at bottom, it
is doubtless the tendency which faith personifies as Anti-Christ.
Nevertheless, in spite of all religions--and they are systems which
one and all maintain the opposite, and seek to establish it in their
mythical way--this fundamental error never becomes quite extinct, but
raises its head from time to time afresh, until universal indignation
compels it to hide itself once more.

Yet, however certain we may feel of the moral significance of life
and the world, to explain and illustrate it, and to resolve the
contradiction between this significance and the world as it is, form
a task of great difficulty; so great, indeed, as to make it possible
that it has remained for me to exhibit the true and only genuine
and sound basis of morality everywhere and at all times effective,
together with the results to which it leads. The actual facts of
morality are too much on my side for me to fear that my theory can
ever be replaced or upset by any other.
