"Strange indeed that after twenty years training in colleges and universities man should reach such a station wherein he will deny the existence of the ideal or that which is not perceptible to the senses. Have you ever stopped to think that the animal already has graduated from such a university? Have you ever realized that the cow is already a professor emeritus of that university? For the cow without hard labor and study is already a philosopher of the superlative degree in the school of nature. The cow denies everything that is not tangible, saying, "I can see! I can eat! Therefore, I believe only in that which is tangible!" Then why should we go to the colleges? Let us go to the cow." ('Abdu’l-Baha, Promulgation, 356-361)
"The modes of living in different countries, and the various views with which men travel in quest of new scenes, having been talked of, a learned gentleman who holds a considerable office in the law, expatiated on the happiness of a savage life; and mentioned an instance of an officer who had actually lived for some time in the wilds of America, of whom, when in that state, he quoted this reflection with an air of admiration, as if it had been deeply philosophical: 'Here am I, free and unrestrained, amidst the rude magnificence of Nature, with this Indian woman by my side, and this gun with which I can procure food when I want it; what more can be desired for human happiness?' It did not require much sagacity to foresee that such a sentiment would not be permitted to pass without due animadversion.
JOHNSON. 'Do not allow yourself, Sir, to be imposed upon by such gross absurdity. It is sad stuff; it is brutish. If a bull could speak, he might as well exclaim, -- Here am I with this cow and this grass; what being can enjoy greater felicity?'" (Boswell, Life of Johnson)
