The other important argument against free will is that it would be inconsistent with what is called the _Conservation of Energy_, since it is said any voluntary act would involve the creation of energy. But this is at least doubtful; for the will might be free as to its acts, were it only able to control energy without producing it. And it could do this if it possessed the power of altering either the time, or the direction of force; deciding, for instance, whether to raise my hand now, or a minute hence, or whether to raise my right hand or my left. And if it possessed either of these powers, it could turn the latent force, which a man possesses, into actual motion when and how it pleased. And it would thus be free as to its acts, without creating any energy at all. We therefore decide on reviewing the whole subject, that man's will is free; since this alone agrees with his own inherent _conviction_, and fully accounts for his variable _conduct_. While, on the other hand, though an _anomaly_ in nature, it is not on that account incredible; nor is it inconsistent with the _conservation of energy_. (4.) _Man knows that his will is free._ Having now decided that man's will is free, little need be said about the next point, which is that man _knows_ that his will is free, since, as we have shown, this is the chief argument for admitting its freedom. There are, however, many other arguments for proving that man believes that he has a free will, for it is shown by his acts. It is this known freedom which enables a man to set before him an end, and deliberately work towards it; in other words, it enables him to _design_, and makes him a _personal being_, as we have used the term. And it is needless to point out that the evidence of human design is universal. Again, human language affords a conclusive proof that man has always and everywhere believed himself to be free; for such terms as _I will_, _I choose_, _I decide_, exist in all languages. However, we need not pursue this subject, since it is undisputed that man _believes_ that he has a free will; and it is taken for granted in all human affairs. (5.) _Man's responsibility for his acts._ By this is meant that a man is responsible for the way in which he uses his freedom; and this seems to follow at once from his knowing that he is free. Moreover, a sense of responsibility is among the inherent convictions of mankind. Of course, there may be exceptions to this as to most other rules; but taking mankind as a whole, he certainly believes in his own responsibility.
