It is said that free-agency is the absence of those obstacles competent to oppose themselves to the actions of man, or to the exercise of his faculties: it is pretended that he is a free agent, whenever, making use of these faculties, he produces the effect he has proposed to himself. In reply to this reasoning, it is sufficient to consider that it in no wise depends upon himself to place or remove the obstacles that either determine or resist him; the motive that causes his action is no more in his own power than the obstacle that impedes him, whether this obstacle or motive be within his own machine or exterior of his person: he is not master of the thought presented to his mind which determines his will; this thought is excited by some cause independent of himself. To be undeceived on the system of his free-agency, man has simply to recur to the motive by which his will is determined, he will always find this motive is out of his own controul. It is said, that in consequence of an idea to which the mind gives birth, man acts freely if he encounters no obstacle. But the question is, what gives birth to this idea in his brain? has he the power either to prevent it from presenting itself, or from renewing itself in his brain? Does not this idea depend either upon objects that strike him exteriorly and in despite of himself, or upon causes that without his knowledge act within himself and modify his brain? Can he prevent his eyes, cast without design upon any object whatever, from giving him an idea of this object, from moving his brain? He is not more master of the obstacles; they are the necessary effects of either interior or exterior causes, which always act according to their given properties. A man insults a coward, who is necessarily irritated against his insulter, but his will cannot vanquish the obstacle that cowardice places to the object of his desire, which is, to resent the insult; because his natural conformation, which does not depend upon himself, prevents his having courage. In this case the coward is insulted in despite of himself, and against his will is obliged patiently to brook the insult he has received. The partizans of the system of free-agency appear ever to have confounded constraint with necessity. Man believes he acts as a free agent, every time he does not see any thing that places obstacles to his actions; he does not perceive that the motive which causes him to will is always necessary, is ever independent of himself. A prisoner loaded with chains is compelled to remain in prison, but he is not a free agent, he is not able to resist the desire to emancipate himself; his chains prevent him from acting, but they do not prevent him from willing; he would save himself if they would loose his fetters, but he would not save himself as a free agent, fear or the idea of punishment would be sufficient motives for his action.
