In relation to the ethical life, Locke declares that happiness is the only idea which reason takes up out of the sphere of pleasure and pain, and yet that if we aim directly at happiness, we shall miss it. What then has to be done is to seek out “the rules and measures of human actions which lead to happiness.” This is the office of ethics, the end of which is virtue, and thus happiness and virtue are one. With Locke moral actions are only those that depend “upon the choice of an understanding and free agent.” The agent here intended is, as pointed out by Mr. Curtis, the man, and not the will. Locke says that the proper question in connection with freedom, is not “whether the will be free, but whether the man be free.” The will is determined by the mind, and liberty is “a power to act, or not to act, according as the mind directs.” In his “Thoughts concerning Education” Locke affirms that “the result of our judgment, upon examination, is what ultimately determines the man, who could not be free, if his will were determined by anything but his own desire, guided by his own judgment.” The position of Locke is, says the author, that of Plato and Kant: Reason is given as the governor of the will, by its sway to constitute it good. Thence we may rightly conclude, that those who are not governed by reason have not true freedom. We have not space to consider the views entertained by Locke on Institutional Ethics, beyond referring to his doctrine that property rights are given only by labor, and not by occupation, and that labor is the source of all values. The latter doctrine cannot now be accepted as sound, whatever may be said as to the former, but Locke deservedly holds a high place as a political economist. He seems indeed to have been a kind of universal genius. Mr. Curtis refers to the remark made of him “that no philosopher since Aristotle has made and recorded so many valuable observations, or given so great a stimulus to human thought.” Any fresh light that can be thrown on the opinions entertained by so profound a thinker, especially on the important question of ethics, is of value and hence we welcome the present work as an acceptable addition to philosophic literature.
