Read the passage and answer the following question:

That freedom means freedom only from foreign domination, is an outworn idea.

Read the passage to answer the question:
To inquire about the meaning or object of one’s own existence or of creation generally has always seemed to me absurd from an objective point of view. And yet everybody has certain ideals that determine the direction of his endeavors and his judgments. In this sense, I have never looked upon ease and happiness as ends in themselves-such an ethical basis I call more proper for a herd of swine. The ideals which have lighted me on my way and time after time given me new courage to face life cheerfully, have been Truth, Goodness, and Beauty. Without the sense of fellowship with men of like mind, of preoccupation with the objective, the eternally unattainable in the field of art and scientific research, life would have seemed to me empty. The ordinary objects of human endeavor property, outward success, luxury-have always seemed to me contemptible.
