Famous quotes containing the words natural and/or occurrences:
“The natural flights of the human mind are not from pleasure to pleasure, but from hope to hope.”
—Samuel Johnson (1709–1784)
“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)
