Marital intercourse is certainly holy, lawful and praiseworthy in itself and profitable to society, yet in certain circumstances it can prove dangerous, as when through excess the soul is made sick with venial sin, or through the violation and perversion of its primary end, killed by mortal sin; such perversion, detestable in proportion to its departure from the true order, being always mortal sin, for it is never lawful to exclude the primary end of marriage which is the procreation of children.

It is utterly false and cruelly arbitrary to put all the play and learning into childhood, all the work into middle age, and all the regrets into old age.

Margaret Mead

Knowing is not simply a material act, since the object that is known always conceals something beyond the empirical datum. All our knowledge, even the most simple, is always a minor miracle, since it can never be fully explained by the material instruments that we apply to it. In every truth there is something more than we would have expected, in the love that we receive there is always an element that surprises us.

Pope Benedict XVI

Self-command is the main discipline.

Ralph Waldo Emerson

Cherish that which is within you, and shut off that which is without for much knowledge is a curse.

Zhuangzi

Yes, King Edward VI lived only a few years, poor boy, but he lived them worthily.

Mark Twain

I am a slow walker, but I never walk backwards.

Abraham Lincoln

But love is blind, and lovers cannot see The pretty follies that themselves commit, For if they could, Cupid himself would blush To see me thus transformed to a boy

William Shakespeare

I don't love studying. I hate studying. I like learning. Learning is beautiful.

Natalie Portman

Bachelors have consciences, married men have wives.

Samuel Johnson

When we were scared about 9/11, we federalized the airport security, we spent millions for body armor for dogs in Ohio. All that over-reaction comes from fear and government - bad combination.

John Stossel

Those who forget good and evil and seek only to know the facts are more likely to achieve good than those who view the world through the distorting medium of their own desires.

Bertrand Russell

If you are sure you understand everything that is going on, you are hopelessly confused.

Walter F. Mondale
