Men act like brutes in so far as the sequences of their perceptions arise through the principle of memory only, like those empirical physicians who have mere practice without theory.

I maintain also that substances, whether material or immaterial, cannot be conceived in their bare essence without any activity, activity being of the essence of substance in general.

I hold that the mark of a genuine idea is that its possibility can be proved, either a priori by conceiving its cause or reason, or a posteriori when experience teaches us that it is in fact in nature.

It can have its effect only through the intervention of God, inasmuch as in the ideas of God a monad rightly demands that God, in regulating the rest from the beginning of things, should have regard to itself.

But in simple substances the influence of one monad over another is ideal only.

It follows from what we have just said, that the natural changes of monads come from an internal principle, since an external cause would be unable to influence their inner being.

The ultimate reason of things must lie in a necessary substance, in which the differentiation of the changes only exists eminently as in their source; and this is what we call God.

Finally there are simple ideas of which no definition can be given; there are also axioms or postulates, or in a word primary principles, which cannot be proved and have no need of proof.

Indeed every monad must be different from every other. For there are never in nature two beings, which are precisely alike, and in which it is not possible to find some difference which is internal, or based on some intrinsic quality.

I also take it as granted that every created thing, and consequently the created monad also, is subject to change, and indeed that this change is continual in each one.

Men act like brutes in so far as the sequences of their perceptions arise through the principle of memory only, like those empirical physicians who have mere practice without theory.

For since it is impossible for a created monad to have a physical influence on the inner nature of another, this is the only way in which one can be dependent on another.

I do not conceive of any reality at all as without genuine unity.

This is why the ultimate reason of things must lie in a necessary substance, in which the differentiation of the changes only exists eminently as in their source; and this is what we call God.

There are also two kinds of truths: truth of reasoning and truths of fact. Truths of reasoning are necessary and their opposite is impossible; those of fact are contingent and their opposite is possible.

When a truth is necessary, the reason for it can be found by analysis, that is, by resolving it into simpler ideas and truths until the primary ones are reached.

Now where there are no parts, there neither extension, nor shape, nor divisibility is possible. And these monads are the true atoms of nature and, in a word, the elements of things.

Music is the pleasure the human mind experiences from counting without being aware that it is counting.

Whence it follows that God is absolutely perfect, since perfection is nothing but magnitude of positive reality, in the strict sense, setting aside the limits or bounds in things which are limited.

By Rice's own standards, the war was well underway by the time he took office. He was a war president the moment he took the oath. But did he act like one?

Under current law volunteers who are not working with an official nonprofit organization are not covered by the Volunteer Protection Act. Therefore, there are absolutely no legal protections for the average American who wishes to volunteer.

Commas in The New Yorker fall with the precision of knives in a circus act, outlining the victim.

I still feel that a movie has to attempt to say something - even if it fails miserably. But I've sort of given up on believing that I'm going to change the world with every film I choose to act in.

I knew I wanted to act, and I was really driven, so I kept going for it. We moved to L.A. full-time when I was 8 or 9.

Maybe I can't act, but I know the gimmicks. I studied acting all my life and know what's good for me.

I've done a lot of acting. I'm not saying I'm the greatest, but I'd love to act, I'd love to sing.

P.C. is just too Big Brother - telling me how I should act and feel.

Act well your part, there all the honour lies.

I'm a 7 o'clock act. My people want to go to a show, a dinner and then go home and go to bed.

For me, romance isn't an over-the-top act. It's someone offering to help and to support me. Or if that person thinks I'm making the wrong decision, he'll tell me. I want him to be honest, because being that honest takes a lot of guts.

I want more children but for the next three years I want to act.

I have to say that it's very few countries that are willing to look back at its past and apologize for its act, or make amends for its act, as the United States had one.

I think unleashing 3,000 smart bombs against the city of Baghdad in the first several days of the war... to me, if those were unleashed against the San Francisco Bay Area, I would call that an act of extreme terrorism.

I cannot sing, dance or act; what else would I be but a talk show host.

My kids act all the time and it's exactly what I used to do.

After the magical act accomplished by Joyce with Ulysses, perhaps we are getting away from it.

Presidents quickly realize that while a single act might destroy the world they live in, no one single decision can make life suddenly better or can turn history around for the good.

A marriage is no amusement but a solemn act, and generally a sad one.

I think it's bad to talk about one's present work, for it spoils something at the root of the creative act. It discharges the tension.

I went to my last three years of high school in New Jersey. I just wanted to act, you know?

Having a child is surely the most beautifully irrational act that two people in love can commit.

You always do what you want to do. This is true with every act. You may say that you had to do something, or that you were forced to, but actually, whatever you do, you do by choice. Only you have the power to choose for yourself.

Soap opera wouldn't be my first choice, but at this point in my life, I would consider a soap. It would allow me to act and still do other things with my life.

Theatre director: a person engaged by the management to conceal the fact that the players cannot act.

Act enthusiastic and you will be enthusiastic.

You have people who can't act and they get all these parts. Paris Hilton falls into her own category. She's made a career out of it.

I really started trying to get my act together in August of 2002.

I cannot consistently, with self respect, do other than I have, namely, to deliberately violate an act which seems to me to be a denial of everything which ideally and in practice I hold sacred.

In the last four years under the Patriot Act, we have seen a great increase in the ability of law enforcement officials to investigate and track terrorists.
