No man can be brave who thinks pain the greatest evil; nor temperate, who considers pleasure the highest good.
Marcus Tullius CiceroFor one day spent well, and agreeably to your precepts, is preferable to an eternity of error.
Marcus Tullius CiceroWhen I consider the wonderful activity of the mind, so great a memory of what is past, and such a capacity of penetrating into the future: when I behold such a number of arts and sciences, and such a multitude of discoveries hence arising,--I believe and am firmly persuaded that a nature which contains so many things within itself cannot be mortal.
