1. For every man self-interest is the supreme law. "The Anarchists are not only utilitarians, but egoists in the farthest and fullest sense."[660] What does self-interest mean? My interest is everything that serves my purposes.[661] It takes in not only the lowest but also "the higher forms of selfishness."[662] Thus, in particular, the interest of society is at the same time that of every individual: "its life is inseparable from the lives of individuals; it is impossible to destroy one without destroying the other."[663] Self-interest is the supreme law for man. "The Anarchists totally discard the idea of moral obligation, of inherent rights and duties."[664] "So far as inherent right is concerned, might is its only measure. Any man, be his name Bill Sykes or Alexander Romanoff, and any set of men, whether the Chinese highbinders or the Congress of the United States, have the right, if they have the power, to kill or coerce other men and to make the entire world subservient to their ends."[665] "The Anarchism of to-day affirms the right of society to coerce the individual and of the individual to coerce society so far as either has the requisite power."[666] 2. From this supreme law Tucker derives "the law of equal liberty."[667] The law of equal liberty is based on every individual's self-interest. For "liberty is the chief essential to man's happiness, and therefore the most important thing in the world, and I want as much of it as I can get."[668] On the other hand, "human equality is a necessity of stable society,"[669] and the life of society "is inseparable from the lives of individuals."[670] Consequently every individual's self-interest demands the equal liberty of all. "Equal liberty means the largest amount of liberty compatible with equality and mutuality of respect, on the part of individuals living in society, for their respective spheres of action."[671] "'Mind your own business' is the only moral law of the Anarchistic scheme."[672] "It is our duty to respect others' rights, assuming the word 'right' to be used in the sense of the limit which the principle of equal liberty logically places upon might."[673]--On the law of equal liberty is founded "the distinction between invasion and resistance, between government and defence. This distinction is vital: without it there can be no valid philosophy of politics."[674]
