Famous quotes containing the words occurrences, nature and/or culture:
“If to be venerated for benevolence, if to be admired for talents, if to be esteemed for patriotism, if to be beloved for philanthropy, can gratify the human mind, you must have the pleasing consolation to know that you have not lived in vain. And I flatter myself that it will not be ranked among the least grateful occurrences of your life to be assured that, so long as I retain my memory, you will be thought on with respect, veneration, and affection by your sincere friend.”
—George Washington (1732–1799)
“It is the nature of an hypothesis, when once a man has conceived it, that it assimulates every thing to itself as proper nourishment; and, from the first moment of your begetting it, it generally grows the stronger by every thing you see, hear, read, or understand. This is of great use.”
—Laurence Sterne (1713–1768)
“Our culture is ill-equipped to assert the bourgeois values which would be the salvation of the under-class, because we have lost those values ourselves.”
