It is not our frowning battlements...or the strength our gallant and disciplined army? These are not our reliance against a resumption of tyranny in our fair land... Our defense is in the preservation of the spirit which prizes liberty as the heritage of all men, in all lands, everywhere.

Similarly, though ahamkara (egotism) is slain in the perfect man, yet enough of its vitality is left to make him carry on the functions of physical life; but it is not sufficient to bind him again into the world.
All the controversialists who have become conscious of the real issue are already saying of our ideal exactly what used to be said of the Socialists' ideal. They are saying that private property is too ideal not to be impossible. They are saying that private enterprise is too good to be true.

Enlightenment is man's leaving his self-caused immaturity. Immaturity is the incapacity to use one's intelligence without the guidance of another. Such immaturity is self-caused if it is not caused by lack of intelligence, but by lack of determination and courage to use one's intelligence without being guided by another. Sapere Aude! Have the courage to use your own intelligence! is therefore the motto of the enlightenment.
