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.

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.

At the end, the realization is that she had to get to a place in her life where she could drop her guard and make peace with the fact that whether she had a small amount of time, that she had to kind of live it completely through, instead of living by the rules.

President Johnson and I have a lot in common. We were both born in small towns and we're both fortunate in the fact that we think we married above ourselves.

The fact is I've been in Massachusetts for the last two weeks, and it seems over the last few days that the price is increasing by the hour at the pump, so there needs to be an aggressive investigation.

In fact, it is a farce to call any being virtuous whose virtues do not result from the exercise of its own reason.

Working-class Americans have waited too long, close to a decade in fact, for an increase in the minimum wage. This has been the second longest period without a pay raise since the Federal minimum wage law was first enacted in 1938.

The fact is, Latinos now own their own lives and I believe they can afford to look back without judgment.

The fact that it's science fiction gives you the license to do anything you want to do.

It has to do with the fact that Ford, for all his greatness, is an Irish egomaniac, as anyone who knows him will say.

I never knew a more presumptuous person than myself. The fact that I say that shows that what I say is true.

I think the fact that I'm so well known to be gay makes it very difficult to have a convincing relationship with a woman on screen. It wouldn't be at all difficult for me to kiss a woman - I'll kiss a frog if you like.

People expect us to be different, but we're not. We're very similar people, and it's because we're so similar and close to each other that we make each other laugh - in fact we make each other laugh more than we make anyone else laugh.

I can't tell you how hard I worked the last year. In fact, I worked so hard that I know I can't maintain that same work level in 2001, so I've got to quit something.

The miracle of light pours over the green and brown expanse of saw grass and of water, shining and slowly moving, the grass and water that is the meaning and the central fact of the Everglades. It is a river of grass.

The key to accepting responsibility for your life is to accept the fact that your choices, every one of them, are leading you inexorably to either success or failure, however you define those terms.

In fact I have nightmares about having children. I want to carry a baby and feel the life within me and in my dream, I do. But every time after it's born, there's this incredible fear, this pounding pulse of fear. It's a real bad nightmare.

All my songs were solo voices. Just me singing. In fact, that was the gimmick - no gimmick. Just singing straight with not too much background.

The fact is that young people are going to have sex whether you like it or not.

We have stabilized our economy. We took over a very sick economy, and we were hemorrhaging 750,000 jobs a month. We have stopped the hemorrhaging. In fact, we had 140,000 job growth last month. And that's what I call progress.

As a matter of fact they'd blacken us down. I guess there's a reason that according to what the Caucasian wanted us to look like. He wanted us to look-if we were Black, then he had his idea of what we look like.

I felt pretty comfortable with Westerns, apart from the fact I couldn't ride.

There are in fact two things, science and opinion; the former begets knowledge, the later ignorance.

Every day some new fact comes to light - some new obstacle which threatens the gravest obstruction. I suppose this is the reason which makes the game so well worth playing.

There is nothing as mysterious as a fact clearly described. I photograph to see what something will look like photographed.

In fact, words are well adapted for description and the arousing of emotion, but for many kinds of precise thought other symbols are much better.

It has long been known that the chemical atomic weight of hydrogen was greater than one-quarter of that of helium, but so long as fractional weights were general there was no particular need to explain this fact, nor could any definite conclusions be drawn from it.

That the apostolic office is temporary, is a plain historical fact.

I knew exactly what I was, and there was no hang-up with me. None whatsoever. The fact that the pigment of my skin maybe being lighter brown than other people of my race, maybe some of them, but you know our race has all colors.

Facts, according to my ideas, are merely the elements of truths, and not the truths themselves; of all matters there are none so utterly useless by themselves as your mere matters of fact.

Science is organized common sense where many a beautiful theory was killed by an ugly fact.

Love is the affinity which links and draws together the elements of the world... Love, in fact, is the agent of universal synthesis.
