“It is certainly true that reason is the most important and the highest rank among all things and, in comparison with other things of this life, the best and something divine. It is the inventor and mentor of all the arts, medicines, laws, and of whatever wisdom, power, virtue, and glory men possess in this life.”

“The delight we take in our senses is an implicit desire to know the ultimate reason for things, the highest cause. The desire for wisdom that philosophy etymologically is is a desire for the highest or divine causes. Philosophy culminates in theology. All other knowledge contains the seeds of contemplation of the divine.”

“Of all the things which wisdom acquires to produce the blessedness of the complete life, for the greatest is the possession of friendship.”

“The finest emotion of which we are capable is the mystic emotion. Herein lies the germ of all art and all true science. Anyone to whom this feeling is alien, who is no longer capable of wonderment and lives in a state of fear is a dead man. To know that what is impenetrable for us really exists and manifests itself as the highest wisdom and the most radiant beauty, whose gross forms alone are intelligible to our poor faculties – this knowledge, this feeling … that is the core of the true religious sentiment. In this sense, and in this sense alone, I rank myself among profoundly religious men.”

“Whatever anybody says, the most important thing in life is to be happy.”

“Is there not one true coin for which all things ought to exchange?- and that is wisdom; and only in exchange for this, and in company with this, is anything truly bought or sold, whether courage, temperance or justice. And is not all true virtue the companion of wisdom, no matter what fears or pleasures or other similar goods or evils may or may not attend her? But the virtue which is made up of these goods, when they are severed from wisdom and exchanged with one another, is a shadow of virtue only, nor is there any freedom or health or truth in her; but in the true exchange there is a purging away of all these things, and temperance, and justice, and courage, and wisdom herself, are a purgation of them.”
