The libertarian approach is a very symmetrical one: the non-aggression principle does not rule out force, but only the initiation of force. In other words, you are permitted to use force only in response to some else's use of force. If they do not use force you may not use force yourself. There is a symmetry here: force for force, but no force if no force was used.
I am the force willing to change direction. I have chose life instead of murder, I am the force, who sits at peace, at least for now, I am the force, who could destroy 1000 lives, I am nothing and everything, I could be a monk and the one who killed the masses, I am nothing and everything, I am a willing force, one way or the other.
The students I've been with these twenty years are looking for a world where it becomes a little easier to love and a lot harder to hate, where learning nonviolence means that we dedicate our hearts, minds, time, and money to a commitment that the force of love, the force of truth, the force of justice, and the force of organized resistance to corrupt power are seen as sane and the force of fists, guns, armies, and bombs insane.
So long as men desire to live together, no man may initiate the use of physical force against others. . . . When a man attempts to deal with me by force, I answer him by force. It is only as retaliation that force may be used and only against the man who starts its use. No, I do not share his evil or sink to his concept of morality: I merely grant him his choice, destruction, the only destruction he had the right to choose: his own.
Evil itself may be relentless. I will grant you that, but love is relentless too. Friendship is a relentless force. Family is a relentless force. Faith is relentless force. The human spirit is relentless, and the human heart outlasts - and can defeat - even the most relentless force of all, which is time.
For Christians above all men are forbidden to correct the stumblings of sinners by force...it is necessary to make a man better not by force but by persuasion. We neither have authority granted us by law to restrain sinners, nor, if it were, should we know how to use it, since God gives the crown to those who are kept from evil, not by force, but by choice.
Saint John Chrysostom
There is in each of us an ancient force that takes and an ancient force that gives. A man finds little difficulty facing that place within himself where the taking force dwells, but it's almost impossible for him to see into the giving force without changing into something other than man. For a woman, the situation is reversed... These things are so ancient within us... that they're ground into each separate cell of our bodies... It's as easy to be overwhelmed by giving as by taking.
Non-violence is backed by the theory of soul-force in which suffering is courted in the hope of ultimately winning over the opponent. But what happens when such an attempt fail to achieve the object? It is here that soul-force has to be combined with physical force so as not to remain at the mercy of tyrannical and ruthless enemy.
The Force is really a way of feeling; it's a way of being with life. It really has nothing to do with weapons. The Force gives you the power to have extrasensory perception and to be able to see things and hear things, read minds and levitate things. It is said that certain creatures are born with a higher awareness of the Force than humans. Their brains are different; they have more midi-chlorians in their cells.
The necessary consequence of man's right to life is his right to self-defense. In a civilized society, force may be used only in retaliation and only against those who initiate its use. All the reasons which make the initiation of physical force an evil, make the retaliatory use of physical force a moral imperative. If some "pacifist" society renounced the retaliatory use of force, it would be left helplessly at the mercy of the first thug who decided to be immoral. Such a society would achieve the opposite of its intention: instead of abolishing evil, it would encourage and reward it.
Can violence and the use of force to effect change upon the universe be left to the young? Do they see what was, what is, and what might yet be? Have they suffered, watched evil fall upon the good, or good upon the evil? Or should the burden of violence be left to those who can bear it most lightly-upon those who have closed their minds or their feelings? How can they understand the suffering that they must inflict? Should the burden of force be laid upon the short-lived, who will not see the consequences of their actions? How can they dispense force with compassion if they can escape the knowledge of what they do?... The greater the force brought to bear, the older and wiser must be the entity who wields it. Wisdom allows sorrow. Age allows experience, and knowledge reinforces wisdom and experience... Those who would bear the burden of force must be those who are strong and do not seek it, for those who seek force would misuse it, and those who are weak would shy from what they must do...

Go! Yes, You! Go! I will not force you to like me; I will not force you to love me. Unconditional love has a condition inside it but there is no you in me. If I know my real me, then I know your real you. I know your value in me and I also know my value in you. If your value is not in me and my value is not in you, then I will not force you to like me; I will not force you to love me, so go!

The most convincing proof of the conversion of heat into living force [vis viva] has been derived from my experiments with the electro-magnetic engine, a machine composed of magnets and bars of iron set in motion by an electrical battery. I have proved by actual experiment that, in exact proportion to the force with which this machine works, heat is abstracted from the electrical battery. You see, therefore, that living force may be converted into heat, and that heat may be converted into living force, or its equivalent attraction through space.

Though we may never be able to comprehend human life, we know certainly that it is a movement, of whatever nature it be. The existence of movement unavoidably implies a body which is being moved and a force which is moving it. Hence, wherever there is life, there is a mass moved by a force. All mass possesses inertia; all force tends to persist
