The Virgin Mary remains in the middle between Christ and humankind. For in the very moment he was conceived and lived, he was full of grace. All other human beings are without grace, both in the first and second conception. But the Virgin Mary, though without grace in the first conception, was full of grace in the second ... whereas other human beings are conceived in sin, in soul as well as in body, and Christ was conceived without sin in soul as well as in body, the Virgin Mary was conceived in body without grace but in soul full of grace.

It is truly a marvelous thing to consider to what greatness Athens arrived in the space of one hundred years after she freed herself from the tyranny of Pisistratus; but, above all, it is even more marvelous to consider the greatness Rome reached when she freed herself from her kings. The reason is easy to understand, for it is the common good and not private gain that makes cities great. Yet, without a doubt, this common good is observed only in republics, for in them everything that promotes it is practised, and however much damage it does to this or that private individual, those who benefit from the said common good are so numerous that they are able to advance in spite of the inclination of the few citizens who are oppressed by it.

Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy. But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. Matthew 5:43-45 (KJV)

I also will ask you one thing, which if ye tell me, I in like wise will tell you by what authority I do these things. The baptism of John, whence was it? from heaven, or of men? 21:24-25 (KJV)

M. Desargues puts me under obligations on account of the pains that it has pleased him to have in me, in that he shows that he is sorry that I do not wish to study more in geometry, but I have resolved to quit only abstract geometry, that is to say, the consideration of questions which serve only to exercise the mind, and this, in order to study another kind of geometry, which has for its object the explanation of the phenomena of nature... You know that all my physics is nothing else than geometry.

I consider as lovers of books not those who keep their books hidden in their store-chests and never handle them, but those who, by nightly as well as daily use thumb them, batter them, wear them out, who fill out all the margins with annotations of many kinds, and who prefer the marks of a fault they have erased to a neat copy full of faults.

What of a truth that is bounded by these mountains and is falsehood to the world that lives beyond?

For it is not death or pain that is to be feared, but the fear of pain or death. Variant: For death or pain is not formidable, but the fear of pain or death.

As to the people; in all these countries the greater part of the people certainly detest war, and most devoutly wish for peace. A very few of them, indeed, whose unnatural happiness depends upon the public misery, may wish for war; but be it yours to decide, whether it is equitable or not, that the unprincipled selfishness of such wretches should have more weight than the anxious wishes of all good men united.

What the great learning teaches, is to illustrate illustrious virtue; to renovate the people; and to rest in the highest excellence. The point where to rest being known, the object of pursuit is then determined; and, that being determined, a calm unperturbedness may be attained to. To that calmness there will succeed a tranquil repose. In that repose there may be careful deliberation, and that deliberation will be followed by the attainment of the desired end.

Like the body the soul can be healthy, youthful, and so on. It can undergo pain, thirst, and hunger. In this physical life, that is, in the visible world, we avoid whatever would defile or deform the body; how much more, then, ought we to avoid that which would tarnish the soul?

But the inner part is the better part; for to it, as both ruler and judge, all these messengers of the senses report the answers of heaven and earth and all the things therein, who said, "We are not God, but he made us." My inner man knew these things through the ministry of the outer man, and I, the inner man, knew all this, I, the soul, through the senses of my body. I asked the whole frame of earth about my God, and it answered, "I am not he, but he made me."

Arts and sciences are not cast in a mould, but are formed and perfected by degrees, by often handling and polishing, as bears leisurely lick their cubs into form.

For my own part, I may desire in general to be other than I am; I may condemn and dislike my whole form, and beg of Almighty God for an entire reformation, and that He will please to pardon my natural infirmity: but I ought not to call this repentance, methinks, no more than the being dissatisfied that I am not an angel or Cato. My actions are regular, and conformable to what I am and to my condition; I can do no better; and repentance does not properly touch things that are not in our power; sorrow does.. I imagine an infinite number of natures more elevated and regular than mine; and yet I do not for all that improve my faculties, no more than my arm or will grow more strong and vigorous for conceiving those of another to be so.

Who then to frail mortality shall trust But limns the water, or but writes in dust.

And not to serve for a table-talk.

[H]ow will one part of the infinite be above, and another below? Or how will it have extremes or a middle? Further still, every sensible body is in place; but the species and differences of place are upward and downward, before and behind, to the right hand and to the left: and these things not only thus subsist with relation to us, and by position, but have a definite subsistence in the universe itself. But it is impossible that these things should be in the infinite: and... that there should be an infinite place. But every body is in place; and therefore it is also impossible that there should be an infinite body. ...[T]herefore ...there is not an infinite body in energy.

What is the first business of one who practices philosophy? To get rid of self-conceit. For it is impossible for anyone to begin to learn that which he thinks he already knows.

Faith is a living, bold trust in God's grace, so certain of God's favor that it would risk death a thousand times trusting in it. Such confidence and knowledge of God's grace makes you happy, joyful and bold in your relationship to God and all creatures. The Holy Spirit makes this happen through faith. Because of it, you freely, willingly and joyfully do good to everyone, serve everyone, suffer all kinds of things, love and praise the God who has shown you such grace.

When Christianity came into the world the task was simply to proclaim Christianity. The same is the case wherever Christianity is introduced into a country the religion of which is not Christianity.

Ten thousand do not turn the scale against a single man of worth.

The tyrant has arisen, and the king and oligarchy and aristocracy and democracy, because men are not contented with that one perfect ruler, and do not believe that there could ever be any one worthy of such power or willing and able by ruling with virtue and knowledge to dispense justice and equity rightly to all, but that he will harm and kill and injure any one of us whom he chooses on any occasion, since they admit that if such a man as we describe should really arise, he would be welcomed and would continue to dwell among them, directing to their weal as sole ruler a perfectly right form of government. But, as the case now stands, since, as we claim, no king is produced in our states who is, like the ruler of the bees in their hives, by birth pre-eminently fitted from the beginning in body and mind, we are obliged, as it seems, to follow in the track of the perfect and true form of government by coming together and making written laws.

Physicians have this advantage: the sun lights their success and the earth covers their failures.

I do not have much liking for the too famous existential philosophy, and, to tell the truth, I think its conclusions false.

The man of virtue makes the difficulty to be overcome his first business, and success only a subsequent consideration: this may be called perfect virtue.

I need not repeat, that the most savage of the savage tribes in the forest, live among each other in amity. Lions show no fierceness to the lion race. The boar does not brandish his deadly tooth against his brother boar. The lynx lives in peace with the lynx. The serpent shews no venom in his intercourse with his fellow serpent; and the loving kindness of wolf to wolf is proverbial.

If a person gave your body to any stranger he met on his way, you would certainly be angry. And do you feel no shame in handing over your own mind to be confused and mystified by anyone who happens to verbally attack you?

It is said in the Book of Poetry, "In silence is the offering presented, and the spirit approached to; there is not the slightest contention." Therefore the superior man does not use rewards, and the people are stimulated to virtue. He does not show anger, and the people are awed more than by hatchets and battle-axes.

Parmenides: If anyone, with his mind fixed on all these objections and others like them, denies the existence of ideas of things, and does not assume an idea under which each individual thing is classed, he will be quite at a loss, since he denies that the idea of each thing is always the same, and in this way he will utterly destroy the power of carrying on discussion... Then what will become of philosophy? To what can you turn, if these things are unknown?

Most men pursue pleasure with such breathless haste that they hurry past it.

Cornered vessel without corners, strange cornered vessel, strange cornered vessel.

Nonsense. You are a military man and should know better. If there is one science into which man has probed continuously and successfully, it is that of military technology. No potential weapon would remain unrealized for ten thousand years.

Printing will tell you such useful things and such interesting things that not being able to read would be as bad as not being able to see.

Do not judge according to appearance, but judge with righteous judgment. (John 7:24) (NASB) Variant translation: Stop judging by mere appearances, and make a right judgment. (NIV)

The essential nature (concerning the soul) cannot be corporeal, yet it is also clear that this soul is present in a particular bodily part, and this one of the parts having control over the rest (heart).

Christ is not valued at all unless He be valued above all.

If you reject absolutely any single sensation without stopping to discriminate with respect to that which awaits confirmation between matter of opinion and that which is already present, whether in sensation or in feelings or in any immediate perception of the mind, you will throw into confusion even the rest of your sensations by your groundless belief and so you will be rejecting the standard of truth altogether. If in your ideas based upon opinion you hastily affirm as true all that awaits confirmation as well as that which does not, you will not escape error, as you will be maintaining complete ambiguity whenever it is a case of judging between right and wrong opinion.

I consider one of the most important duties of any scientist the teaching of science to students and to the general public.

There always comes a time in history when the person who dares to say that 2+2=4 is punished by death. And the issue is not what reward or what punishment will be the outcome of that reasoning. The issue is simply whether or not 2+2=4.

The similarity between Christ and Socrates consists essentially in their dissimilarity. Just as philosophy begins with doubt, so also a life that may be called human begins with irony.

When one cultivates to the utmost the principles of his nature, and exercises them on the principle of reciprocity, he is not far from the path. What you do not like when done to yourself, do not do to others.

Men all say, "We are wise"; but being driven forward and taken in a net, a trap, or a pitfall, they know not how to escape. Men all say, "We are wise"; but happening to choose the course of the Mean, they are not able to keep it for a round month.

But the Jews are so hardened that they listen to nothing; though overcome by testimonies they yield not an inch. It is a pernicious race, oppressing all men by their usury and rapine. If they give a prince or magistrate a thousand florins, they extort twenty thousand from the subjects in payment. We must ever keep on guard against them.

Truth, like light, blinds. Falsehood, on the contrary, is a beautiful twilight that enhances every object.

If a woman becomes weary and at last dead from bearing, that matters not; let her only die from bearing, she is there to do it.

Peace be with you. Receive my peace unto yourselves. Beware that no one lead you astray saying Lo here or lo there! For the Son of Man is within you. Follow after Him! Those who seek Him will find Him. Go then and preach the gospel of the Kingdom. Do not lay down any rules beyond what I appointed you, and do not give a law like the lawgiver lest you be constrained by it. Chapter 4. Peace be with you. Receive my peace for yourselves. Take heed lest anyone lead you astray with the words, 'Lo, here!' or 'Lo, there!' for the Son of Man is within you. Follow him; those who seek him will find him. Go, therefore, and preach the Gospel of the Kingdom. I have left no commandment but what I have commanded you, and I have given you no law, as the lawgiver did, lest you be bound by it. Variant translation.

The first and most necessary topic in philosophy is that of the use of moral theorems, such as, "We ought not to lie;" the second is that of demonstrations, such as, "What is the origin of our obligation not to lie;" the third gives strength and articulation to the other two, such as, "What is the origin of this is a demonstration." For what is demonstration? What is consequence? What contradiction? What truth? What falsehood? The third topic, then, is necessary on the account of the second, and the second on the account of the first. But the most necessary, and that whereon we ought to rest, is the first. But we act just on the contrary. For we spend all our time on the third topic, and employ all our diligence about that, and entirely neglect the first.

If it is my interest to have a farm, it is my interest to take it away from my neighbour; if it is my interest to have a cloak, it is my interest also to steal it from a bath. This is the source of wars, seditions, tyrannies, plots.

It is the part of cowardice, not of courage, to go and crouch in a hole under a massive tomb, to avoid the blows of fortune.
