in the conditions in
physical nature. All phenomena of which the ultimate principle cannot
be derived from the world of sense are an indirect representation of
the upper-sensuous element.

And how does one succeed in representing something that is above nature
without having recourse to supernatural means? What can this phenomenon
be which is accomplished by natural forces--otherwise it would not be a
phenomenon--and yet which cannot be derived from physical causes without
a contradiction? This is the problem; how can the artist solve it?

It must be remembered that the phenomena observable in a man in a state
of passion are of two kinds. They are either phenomena connected simply
with animal nature, and which, therefore, only obey the physical law,
without the will being able to master them, or the independent force in
him being able to exercise an immediate influence over them. It is the
instinct which immediately produces these phenomena, and they obey
blindly the laws of instinct. To this kind belong, for example, the
organs of the circulation of the blood, of respiration, and all the
surface of the skin. But, moreover, the other organs, and those subject
to the will, do not always await the decision of the will; and often
instinct itself sets them immediately in play, especially when the
physical state is threatened with pain or with danger. Thus, the
movements of my arm depend, it is true, on my will; but if I place my
hand, without knowing it, on a burning body, the movement by which I draw
it back is certainly not a voluntary act, but a purely instinctive
phenomenon. Nay more, speech is assuredly subject to the empire of the
will, and yet instinct can also dispose of this organ according to its
whim, and even of this and of the mind, without consulting beforehand the
will, directly a sharp pain, or even an energetic affection, takes us by
surprise. Take the most impassible stoic and make him see suddenly
something very wonderful, or a terrible and unexpected object. Fancy
him, for example, present when a man slips and falls to the bottom of an
abyss. A shout, a resounding cry, and not only inarticulate, but a
distinct word will escape his lips, and nature will have acted in him
before the will: a certain proof that there are in man phenomena which
cannot be referred to his person as an intelligence, but only to his
instinct as a natural force.

But there is also in man a second order of phenomena, which are su
