I don’t use Twitter for bad.

It is forbidden to kill; therefore all murderers are punished unless they kill in large numbers and to the sound of trumpets.

Well, I thought the deal was, when you went to work for the government you weren’t supposed to make money!

So far as I am concerned, I could not be accused of having set eyes, or having wished to set eyes, upon Darius‘ wife: on the contrary, I have refused even to listen to those who spoke to me of her beauty.

I’m very active on social media and see the huge impact it has on engaging with fans and being able to have a voice.

I can tell you this: If I’m ever in a position to call the shots, I’m not going to rush to send somebody else’s kids into a war.

What is human warfare but just this; an effort to make the laws of God and nature take sides with one party.

In matters of truth and justice, there is no difference between large and small problems, for issues concerning the treatment of people are all the same.

Abortion is clearly wrong.

I love to go to the zoo. But not on Sunday. I don’t like to see the people making fun of the animals, when it should be the other way around.

For I can raise no money by vile means.

One of the great questions of philosophy is, do we innately have morality, or do we get it from celestial dictation? A study of the Ten Commandments is a very good way of getting into and resolving that issue.

There are no easy answers, but there are simple answers. We must have the courage to do what we know is morally right.

Morality is simply the attitude we adopt towards people whom we personally dislike.

Charity creates a multitude of sins.

On some positions, Cowardice asks the question, ‚Is it safe?‘ Expediency asks the question, ‚Is it politic?‘ And Vanity comes along and asks the question, ‚Is it popular?‘ But Conscience asks the question, ‚Is it right?‘

When you look at a corporation, just like when you look at a slave owner, you want to distinguish between the institution and the individual. So slavery, for example, or other forms of tyranny, are inherently monstrous. The individuals participating in them may be the nicest guys you can imagine.

When you have to kill a man, it costs nothing to be polite.

I mean, we’ve built a lot of products that we think are good, and will help people share photos and share videos and write messages to each other. But it’s really all about how people are spreading Facebook around the world in all these different countries. And that’s what’s so amazing about the scale that it’s at today.

About morals, I know only that what is moral is what you feel good after and what is immoral is what you feel bad after.

MySpace is my wife… Facebook is my mistress.

To say that you can kill in the name of God is blasphemy.

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.

Men never do evil so completely and cheerfully as when they do it from religious conviction.

People at Facebook are fairly used to the press being nice to us or not nice to us.

Justice in the life and conduct of the State is possible only as first it resides in the hearts and souls of the citizens.

Where there is no opposition to evil, it multiplies.

Morality is contraband in war.

When I do good I feel good, when I do bad I feel bad, and that’s my religion.

MySpace is an addiction.

Ingratitude is the essence of vileness.

He who steals a little steals with the same wish as he who steals much, but with less power.

Labor to keep alive in your breast that little spark of celestial fire, called conscience.

Of all the varieties of virtues, liberalism is the most beloved.

Our role is to be a platform for making all of these apps more social, and it’s kind of an extension of what we see happening on the web, with the exception of mobile, which I think will be even more important than the web in a few years – maybe even sooner.

Laws control the lesser man… Right conduct controls the greater one.

A leader who doesn’t hesitate before he sends his nation into battle is not fit to be a leader.

I don’t believe in killing whatever the reason!

Every actual State is corrupt. Good men must not obey laws too well.

The one thing that doesn’t abide by majority rule is a person’s conscience.

One may no more live in the world without picking up the moral prejudices of the world than one will be able to go to hell without perspiring.

States are not moral agents, people are, and can impose moral standards on powerful institutions.

Always recognize that human individuals are ends, and do not use them as means to your end.

The real question for me is, do people have the tools that they need in order to make those decisions well? And I think that it’s actually really important that Facebook continually makes it easier and easier to make those decisions… If people feel like they don’t have control over how they’re sharing things, then we’re failing them.

Those who have virtue always in their mouths, and neglect it in practice, are like a harp, which emits a sound pleasing to others, while itself is insensible of the music.

Idealism is the noble toga that political gentlemen drape over their will to power.

This is our commitment to users and the people who use our service, is that Facebook’s a free service. It’s free now. It will always be free. We make money through having advertisements and things like that.

At Facebook, we build tools to help people connect with the people they want and share what they want, and by doing this we are extending people’s capacity to build and maintain relationships.

Now the playbook is we build AI tools to go find these fake accounts, find coordinated networks of inauthentic activity, and take them down; we make it much harder for anyone to advertise in ways that they shouldn’t be.

It is as hard and severe a thing to be a true politician as to be truly moral.

If we cut up beasts simply because they cannot prevent us and because we are backing our own side in the struggle for existence, it is only logical to cut up imbeciles, criminals, enemies, or capitalists for the same reasons.

Doing what’s right isn’t the problem. It is knowing what’s right.

You’re morally tainted if you don’t treat both the accuser and the accused with fairness and with respect, and with due process.

A man is ethical only when life, as such, is sacred to him, that of plants and animals as that of his fellow men, and when he devotes himself helpfully to all life that is in need of help.

One of the things that we’re trying to do with Creative Labs and all our experiences is explore things that aren’t all tied to Facebook identity. Some things will be, but not everything will have to be, because there are some sets of experiences that are just better with other identities.

Justice is the set and constant purpose which gives every man his due.

Nonviolence is a good policy when the conditions permit.

Should surveillance be usable for petty crimes like jaywalking or minor drug possession? Or is there a higher threshold for certain information? Those aren’t easy questions.

Successful and fortunate crime is called virtue.

To prefer evil to good is not in human nature; and when a man is compelled to choose one of two evils, no one will choose the greater when he might have the less.

I actually don’t read most of the coverage about Facebook. I try to learn from getting input from people who use our services directly more than from pundits.
