though it may be involuntary
and provoked by a sentiment, ought not to be confounded with those purely
instinctive movements that proceed from physical sensibility. Physical
instinct is not a free agent, and that which it executes is not an act of
the person; I understand then here exclusively, by sympathetic movements,
those which accompany a sentiment, a disposition of the moral order.

The question that now presents itself is this: Of these two kinds of
movement, having their principle in the person, which is capable of
grace?

That which we are rigorously forced to distinguish in philosophic
analysis is not always separated also in the real. Thus it is rare that
we meet intentional movements without sympathetic movements, because the
will determines the intentional movements only after being decided itself
by the moral sentiments which are the principle of the sympathetic
movements. When a person speaks, we see his looks, his lineaments, his
hands, often the whole person all together speaks to us; and it is not
rare that this mimic part of the discourse is the most eloquent. Still
more there are cases where an intentional movement can be considered at
the same time as sympathetic; and it is that which happens when something
involuntary mingles with the voluntary act which determines this
movement.

I will explain: the mode, the manner in which a voluntary movement is
executed, is not a thing so exactly determined by the intention which is
proposed by it that it cannot be executed in several different ways.
Well, then, that which the will or intention leaves undetermined can be
sympathetically determined by the state of moral sensibility in which the
person is found to be, and consequently can express this state. When I
extend the arm to seize an object, I execute, in truth, an intention, and
the movement I make is determined in general by the end that I have in
view; but in what way does my arm approach the object? how far do the
other parts of my body follow this impulsion? What will be the degree of
slowness or of the rapidity of the movement? What amount of force shall
I employ? This is a calculation of which my will, at the instant, takes
no account, and in consequence there is a something left to the
discretion of nature.

But nevertheless, though that part of the movement is not determined by
the intention itself, it must be decided at length in one way or the
other, and the reason is that the manner in w
