Learned we may be with another man's learning: we can only be wise with wisdom of our own: [I hate a sage who is not wise for himself]
EuripidesWe must take care of our minds because we cannot benefit from beauty when our brains are missing.
EuripidesYoung man, two are the forces most precious to mankind. The first is Demeter, the Goddess. She is the Earth -- or any name you wish to call her -- and she sustains humanity with solid food. Next came Dionysus, the son of the virgin, bringing the counterpart to bread: wine and the blessings of life's flowing juices. His blood, the blood of the grape, lightens the burden of our mortal misery. Though himself a God, it is his blood we pour out to offer thanks to the Gods. And through him, we are blessed.
