Sanity is a madness put to good use.

George Santayana (December 16, 1863, Madrid, Spain – September 26, 1952, Rome, Italy), was a Spanish-American philosopher, essayist, poet, and novelist. A lifelong Spanish citizen, Santayana was raised and educated in the United States, wrote in English and is generally considered an American man of letters. Of his nearly 89 years, he spent 39 in the U.S. Santayana is perhaps best known as an aphorist, most famously for his oft-misquoted remark "Those who cannot remember the past are condemned to repeat it."^[1] Similarly, a line of Santayana's, "Only the dead have seen the end of war,"^[2] is often falsely attributed to Plato
