“Be secret and exult,
Because of all things known
That is most difficult.”

“If all men by nature desire to know, then they desire most of all the greatest knowledge of science. So the Philosopher argues in chap. 2 of his first book of the work [Metaphisics]. And he immediately indicates what the greatest science is, namely the science which is about those things that are most knowable. But there are two senses in which things are said to be maximally knowable: either [1] because they are the first of all things known and without them nothing else can be known; or [2] because they are what are known most certainly. In either way, however, this science is about the most knowable. Therefore, this most of all is a science and, consequently, most desirable…”
sic: si omnes homines natura scire desiderant, ergo maxime scientiam maxime desiderabunt. Ita arguit Philosophus I huius cap. 2. Et ibidem subdit: "quae sit maxime scientia, illa scilicet quae est circa maxime scibilia". Maxime autem dicuntur scibilia dupliciter: uel quia primo omnium sciuntur sine quibus non possunt alia sciri; uel quia sunt certissima cognoscibilia. Utroque autem modo considerat ista scientia maxime scibilia. Haec igitur est maxime scientia, et per consequens maxime desiderabilis.

“The most difficult secret for a man to keep is his own opinion of himself.”

“The Most difficult thing but an essential one – is to love Life, to love it even while one suffers, because Life is all, Life is God, and to love Life means to love God.”

“The things that are most precious to us are sometimes the most secret.”

“Truth in all its kinds is most difficult to win; and truth in medicine is the most difficult of all.”

“Sometimes simple things are the most difficult things to achieve.”

“The most difficult thing is not to want anything.”

“A secret is a strange thing. There are three kinds of secrets. One is the sort everyone knows about, the sort you need at least two people for. One to keep it. One to never know. The second is a harder kind of secret: one you keep from yourself. Every day, thousands of confessions are kept from their would-be confessors, none of these people knowing that their never-admitted secrets all boil down to the same three words: I am afraid. And then there is the third kind of secret, the most hidden kind. A secret no one knows about. Perhaps it was known once, but was taken to the grave. Or maybe it is a useless mystery, arcane and lonely, unfound because no one ever looked for it. Sometimes, some rare times, a secret stays undiscovered because it is something too big for the mind to hold. It is too strange, too vast, too terrifying to contemplate. All of us have secrets in our lives. We’re keepers or keptfrom, players or played. Secrets and cockroaches — that’s what will be left at the end of it all.”
