Nothing has such power to broaden the mind as the ability to investigate systematically and truly all that comes under thy observation in life.
Marcus AureliusFor a man can lose neither the past nor the future; for how can one take from him that which is not his? So remember these two points: first, that each thing is of like form from everlasting and comes round again in its cycle, and that it signifies not whether a man shall look upon the same things for a hundred years or two hundred, or for an infinity of time; second, that the longest lived and the shortest lived man, when they come to die, lose one and the same thing.
Marcus AureliusI have often wondered how it is that every man loves himself more than all the rest of men, but yet sets less value on his own opinions of himself than on the opinions of others.
