Someone once asked me, "If you had your choice, Dr. Asimov, would it be women or writing?" My answer was, "Well, I can write for twelve hours at a time without getting tired."

This heart within me I can feel, and I judge that it exists. This world I can touch, and I likewise judge that it exists. There ends all my knowledge, and the rest is construction. For if I try to seize this self of which I feel sure, if I try to define and to summarize it, it is nothing but water slipping through my fingers. I can sketch one by one all the aspects it is able to assume, all those likewise that have been attributed to it, this upbringing, this origin, this ardor or these silences, this nobility or this vileness. But aspects cannot be added up. This very heart which is mine will forever remain indefinable to me. Between the certainty I have of my existence and the content I try to give to that assurance, the gap will never be filled. Forever I shall be a stranger to myself.

It is more blessed to give than to receive. Acts 20:35b

A genius and an Apostle are qualitatively different, they are definitions which each belong in their own spheres: the sphere of immanence, and the sphere of transcendence.

One who seeks will find, and for [one who knocks] it will be opened (94)

That body is heavier than another which, in an equal bulk, moves downward quicker.

With men this is impossible; but with God all things are possible. 19:26 (KJV)

O ye of little faith, why reason ye among yourselves, because ye have brought no bread? Do ye not yet understand, neither remember the five loaves of the five thousand, and how many baskets ye took up? Neither the seven loaves of the four thousand, and how many baskets ye took up? How is it that ye do not understand that I spake it not to you concerning bread, that ye should beware of the leaven of the Pharisees and of the Sadducees? 16:8-11 (KJV)

Friend, wherefore art thou come? 26:50 (KJV) Said to Judas.

I may live for thirty years, or perhaps forty, or maybe just one day: therefore I have resolved to use this day, or whatever I have to say in these thirty years or whatever I have to say this one day I may have to live - I have resolved to use it in such a way that if not one day in my whole past life has been used well, this one by the help of God will be.

If any man will come after me, let him deny himself, and take up his cross, and follow me. For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it. For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul? For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works. Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom. 16:24-28 (KJV)

Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve. 4:10 (KJV) Said to Satan.

Outside of that single fatality of death, everything, joy or happiness, is liberty.

Economics is on the side of humanity now.

What the age needs is not a genius - it has had geniuses enough, but a martyr, who in order to teach men to obey would himself be obedient unto death. What the age needs is awakening. And therefore someday, not only my writings but my whole life, all the intriguing mystery of the machine will be studied and studied. I never forget how God helps me and it is therefore my last wish that everything may be to his honour.

Indeed, it may well be argued that one reason for the decline in science, art, and literature was the increasing absorption of the better minds into a new sort of intellectual pursuit, theology.

I have never definitely broken with Christianity nor renounced it. To attack it has never been my thought. No, from the time when there could be any question of the employment of my powers, I was firmly determined to employ them all to defend Christianity, or in any case to present it in its true form.

Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you. Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day. For my flesh is meat indeed, and my blood is drink indeed. He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him. 6:53-56

Elias truly shall first come, and restore all things. But I say unto you, That Elias is come already, and they knew him not, but have done unto him whatsoever they listed. Likewise shall also the Son of man suffer of them. 17:11-12 (KJV)

Existence is illusory and it is eternal.

You have already grasped that Sisyphus is the absurd hero. He is, as much through his passions as through his torture. His scorn of the gods, his hatred of death, and his passion for life won him that unspeakable penalty in which the whole being is exerted toward accomplishing nothing. This is the price that must be paid for the passions of this earth. Nothing is told us about Sisyphus in the underworld. Myths are made for the imagination to breathe life into them.

The kingdom of heaven is like unto leaven, which a woman took, and hid in three measures of meal, till the whole was leavened. 13:33 (KJV)

Go and shew John again those things which ye do hear and see: The blind receive their sight, and the lame walk, the lepers are cleansed, and the deaf hear, the dead are raised up, and the poor have the gospel preached to them. And blessed is he, whosoever shall not be offended in me. 11:4-6 (KJV)

The natural way of doing this [seeking scientific knowledge or explanation of fact] is to start from the things which are more knowable and obvious to us and proceed towards those which are clearer and more knowable by nature; for the same things are not 'knowable relatively to us' and 'knowable' without qualification. So in the present inquiry we must follow this method and advance from what is more obscure by nature, but clearer to us, towards what is more clear and more knowable by nature. Now what is to us plain and obvious at first is rather confused masses, the elements and principles of which became known to us by later analysis...

He was extremely important to his contemporaries, who wanted nothing more than to see in him the Expected One; they wanted almost to press it upon him and and to force him into the role - but that he then refuses to be that!

So when the universe was quickened with soul, God was well pleased; and he bethought him to make it yet more like its type. And whereas the type is eternal and nought that is created can be eternal, he devised for it a moving image of abiding eternity, which we call time. And he made days and months and years, which are portions of time; and past and future are forms of time, though we wrongly attribute them also to eternity. For of eternal Being we ought not to say 'it was', 'it shall be', but 'it is' alone: and in like manner we are wrong in saying 'it is' of sensible things which become and perish; for these are ever fleeting and changing, having their existence in time.

When we observe a thing, we see too much in it, we fall under the spell of the wealth of empirical detail which prevents us from clearly perceiving the notional determination which forms the core of the thing. The problem is thus not that of how to grasp the multiplicity of determinations, but rather to abstract from them, how to constrain our gaze and teach it to grasp only the notional determinism.

For by the hands of the Father, that is, by the Son and the Holy Spirit, man, and not [merely] a part of man, was made in the likeness of God. For by the hands of the Father, that is, by the Son and the Holy Spirit, man, and not [merely] a part of man, was made in the likeness of God. Against Heresies: Book V, Ch. Chapter VI.—God will bestow salvation upon the whole nature of man, consisting of body and soul in close union, since the Word took it upon Him, and adorned with the gifts of the Holy Spirit, of whom our bodies are, and are termed, the temples.

Once in his early youth a man allowed himself to be so far carried away in an overwrought irresponsible state as to visit a prostitute. It is all forgotten. Now he wants to get married. Then anxiety stirs. He is tortured day and night with the thought that he might possibly be a father, that somewhere in the world there could be a created being who owed his life to him. He cannot share his secret with anyone; he does not even have any reliable knowledge of the fact. –For this reason the incident must have involved a prostitute and taken place in the wantonness of youth; had it been a little infatuated or an actual seduction, it would be hard to imagine that he could know nothing about it, but now this this very ignorance is the basis of his agitated torment. On the other hand, precisely because of the rashness of the whole affair, his misgivings do not really start until he actually falls in love.

If anyone can be considered the greatest writer who ever lived, it is Shakespeare.

The ancients, even though they believed in destiny, believed primarily in nature, in which they participated wholeheartedly. To rebel against nature amounted to rebelling against oneself.

A friend is one soul abiding in two bodies. p. 188; also reported in various sources as:Friendship is a single soul dwelling in two bodies. A true friend is one soul in two bodies. Love is composed of a single soul inhabiting two bodies. What is a friend? A single soul dwelling in two bodies.

Trantor could win even such a war, but perhaps not without paying a price that would make victory only a pleasanter name for defeat.

One might think that a period which, in a space of fifty years, uproots, enslaves, or kills seventy million human beings should be condemned out of hand. But its culpability must still be understood... In more ingenuous times, when the tyrant razed cities for his own greater glory, when the slave chained to the conqueror's chariot was dragged through the rejoicing streets, when enemies were thrown to the wild beasts in front of the assembled people, the mind did not reel before such unabashed crimes, and the judgment remained unclouded. But slave camps under the flag of freedom, massacres justified by philanthropy or by a taste for the superhuman, in one sense cripple judgment. On the day when crime dons the apparel of innocence, through a curious transposition peculiar to our times, it is innocence that is called upon to justify itself.

Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme: But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation. (Mark 3:28-29) (KJV)

The whole business is the crudest sort of stratagem, since we have no way of foreseeing it to the end. It is a mere paying out of rope on the chance that somewhere along the length of it will be a noose.

The victor and the one who keeps My works to the end: I will give him authority over the nations— and He will shepherd them with an iron scepter; He will shatter them like pottery— just as I have received [this] from My Father. Revelation 2:26-27

But as more arts were invented, and some were directed to the necessities of life, others to recreation, the inventors of the latter were naturally always regarded as wiser than the inventors of the former, because their branches of knowledge did not aim at utility. ... This is why the mathematical arts were founded in Egypt; for there the priestly caste was allowed to be at leisure.

Those who assert that the mathematical sciences say nothing of the beautiful or the good are in error. For these sciences say and prove a great deal about them; if they do not expressly mention them, but prove attributes which are their results or definitions, it is not true that they tell us nothing about them. The chief forms of beauty are order and symmetry and definiteness, which the mathematical sciences demonstrate in a special degree.

Take a book, the poorest one written, but read it with the passion that it is the only book you will read-ultimately you will read everything out of it, that is, as much as there was in yourself, and you could never get more out of reading, even if you read the best of books.

It is simplicity that makes the uneducated more effective than the educated when addressing popular audiences.
