sleep when experiencing a terrible nightmare. However, most suicides were seen as an act of the will, as it takes place when one denies life's pains, and is thus different from ascetic renunciation of the will, which denies life's pleasures. According to Schopenhauer, moral freedom—the highest ethical aim—is to be obtained only by a denial of the will to live. Far from being a denial, suicide is an emphatic assertion of this will. For it is in fleeing from the pleasures, not from the sufferings of life, that this denial consists. When a man destroys his existence as an individual, he is not by any means destroying his will to live. On the contrary, he would like to live if he could do so with satisfaction to himself; if he could assert his will against the power of circumstance; but circumstance is too strong for him. Schopenhauer also addressed arguments against suicide. "That a man who no longer wishes to live for himself must go on living merely as a machine for others to use is an extravagant demand." Libertarianism Libertarianism asserts that a person's life belongs only to them, and no other person has the right to force their own ideals that life must be lived. Rather, only the individual involved can make such a decision, and whatever decision they make should be respected. Philosopher and psychiatrist Thomas Szasz goes further, arguing that suicide is the most basic right of all. If freedom is self-ownership—ownership over one's own life and body—then the right to end that life is the most basic of all. If others can force you to live, you do not own yourself and belong to them. Jean Améry, in his book On Suicide: a Discourse on Voluntary Death (originally published in German in 1976), provides a moving insight into the suicidal mind. He argues forcefully and almost romantically that suicide represents the ultimate freedom of humanity, justifying the act with phrases such as "we only arrive at ourselves in a freely chosen death" and lamenting "ridiculously everyday life and its alienation". Améry killed himself in 1978. Philosophical thinking in the 19th and 20th century has led, in some cases, beyond thinking in terms of pro-choice, to the point that suicide is no longer a last resort, or even something that one must justify, but something that one must justify doing. Many forms of existentialist thinking essentially
