Liberty is the most jealous and exacting mistress that can beguile the brain and soul of man.

The lowest standards of ethics of which a right-thinking man can possibly conceive is taught to the common soldier whose trade is to shoot his fellow men. In youth he may have learned the command, 'Thou shalt not kill,' but the ruler takes the boy just as he enters manhood and teaches him that his highest duty is to shoot a bullet through his neighbor's heart - and this, unmoved by passion or feeling or hatred, and without the least regard to right or wrong, but simply because his ruler gives the word.
