It would take six months to get to Mars if you go there slowly, with optimal energy cost. Then it would take eighteen months for the planets to realign. Then it would take six months to get back, though I can see getting the travel time down to three months pretty quickly if America has the will.

Thanksgiving dinners take eighteen hours to prepare. They are consumed in twelve minutes. Half-times take twelve minutes. This is not coincidence.

Pure phenomenology claims to be the science of pure phenomena. This concept of the phenomenon, which was developed under various names as early as the eighteenth century without being clarified, is what we shall have to deal with first of all.

The poetry from the eighteenth century was prose; the prose from the seventeenth century was poetry.

Since I've been home-schooled since sixth grade, I've practiced six to seven hours a day. I wake up, practice for three hours in the morning, eat lunch, and then go out and play eighteen or more holes.

Mom and Pop were just a couple of kids when they got married. He was eighteen, she was sixteen and I was three.

There is no greater privilege in living than bringing a tiny new human being into the world and then trying to raise him or her properly during the next eighteen years. Doing that job right requires all the intelligence, wisdom, and determination you will be able to muster from day to day.

My divorce came to me as a complete surprise. That's what happens when you haven't been home in eighteen years.

I have the body of an eighteen year old. I keep it in the fridge.

The Resurrection miracle is nothing to you and me if it is only an event of eighteen centuries bygone. Unless we can live the immortal life - unless we can receive God to his own home in these hearts of ours - the texts are nothing to us unless these daily lives illustrate them.

Until I was eighteen, I did not know that you could study fashion design or art. I really didn't know. I already had my nose in the art world; I was already looking at things, but I didn't really get it that you could study that because my school was a very different environment.

Eighteenth century American furniture and the design of the architects Greene and Greene are my special love.

Dominant and emerging forms of interpersonal communication have to find their way into literary language somehow - think of the epistolary novels of the eighteenth and nineteenth centuries.

Throughout the European Middle Ages and Renaissance, Latin was the language of learning and international communication. But in the early modern period, it was gradually displaced by French. By the eighteenth century, all the world - or at least all of Europe - aspired to be Parisian.

I work in a business environment forty hours a week, and writing is what I do to unwind. It allows me to transport myself to a happy place where I can indulge my hopes, beliefs, aspirations and fantasies. It also allows me to live and breathe a topic for eighteen months while I'm researching and writing.

For us lads of eighteen they ought to have been mediators and guides to the world of maturity, the world of work, of duty, of culture, of progress -- to the future.

"Were these boys in their right minds? Here were two boys with good intellect, one eighteen and one nineteen. They had all the prospects that life could hold out for any of the young; one a graduate of Chicago and another of Ann Arbor; one who had passed his examination for the Harvard Law School and was about to take a trip in Europe,--another who had passed at Ann Arbor, the youngest in his class, with three thousand dollars in the bank. Boys who never knew what it was to want a dollar; boys who could reach any position that was to boys of that kind to reach; boys of distinguished and honorable families, families of wealth and position, with all the world before them. And they gave it all up for nothing, for nothing! They took a little companion of one of them, on a crowded street, and killed him, for nothing, and sacrificed everything that could be of value in human life upon the crazy scheme of a couple of immature lads.

Life would be infinitely happier if we could only be born at the age of eighty and gradually approach eighteen.

In the eighteenth century, philosophers considered the whole of human knowledge, including science, to be their field and discussed questions such as: Did the universe have a beginning? However, in the nineteenth and twentieth centuries, science became too technical and mathematical for the philosophers, or anyone else except a few specialists. Philosophers reduced the scope of their inquiries so much that Wittgenstein, the most famous philosopher of this century, said, "The sole remaining task for philosophy is the analysis of language." What a comedown from the great tradition of philosophy from Aristotle to Kant!

By the middle of the eighteenth century the black slave had sunk, with hushed murmurs, to his place at the bottom of a new economic system, and was unconsciously ripe for a new philosophy of life. Nothing suited his condition then better than the doctrines of passive submission embodied in the newly learned Christianity. Slave masters early realized this, and cheerfully aided religious propaganda within certain bounds. The long system of repression and degradation of the Negro tended to emphasize the elements of his character which made him a valuable chattel: courtesy became humility, moral strength degenerated into submission, and the exquisite native appreciation of the beautiful became an infinite capacity for dumb suffering. The Negro, losing the joy of this world, eagerly seized upon the offered conceptions of the next; the avenging Spirit of the Lord enjoining patience in this world, under sorrow and tribulation until the Great Day when He should lead His dark children home,-this became his comforting dream.

"Imagination is not, as some poets have thought, simply synonymous with good. It may be either good or evil. As long as art remained primarily mimetic, the evil which imagination could do was limited by nature. Again, as long as it was treated as an amusement, the evil which it could do was limited in scope. But in an age when the connection between imagination and figuration is beginning to be dimly realized, when the fact of the directionally creator relation is beginning to break through into consciousness, both the good and the evil latent in the working of imagination begin to appear unlimited. We have seen in the Romantic movement an instance of the way in which the making of images may react upon the collective representations. It is a fairly rudimentary instance, but even so it has already gone beyond the dreams and responses of a leisured few. The economic and social structure of Switzerland is noticeably affected by its tourist industry, and that is due only in part to increased facilities of travel. It is due not less to the condition that (whatever may be said about their 'particles') the mountains which twentieth-century man sees are not the mountains which eighteenth-century man saw.

I know this goes without saying, but Stonehenge really was the most incredible accomplishment. It took five hundred men just to pull each sarsen, plus a hundred more to dash around positioning the rollers. Just think about it for a minute. Can you imagine trying to talk six hundred people into helping you drag a fifty-ton stone eighteen miles across the countryside and muscle it into an upright position, and then saying, 'Right, lads! Another twenty like that, plus some lintels and maybe a couple of dozen nice bluestones from Wales, and we can party!' Whoever was the person behind Stonehenge was one dickens of a motivator, I'll tell you that.

That woman speaks eighteen languages, and can't say 'No' in any of them.

Everyone wanted to believe that endless love was possible. She'd believed in it once too, back when she was eighteen. But she knew that love was messy, just like life. It took turns that people couldn't foresee or even understand, leaving a long trail of regret in its wake. And almost always, those regrets led to the kinds of what if questions that could never be answered.
