Everyone has a code of conduct, whether explicit or unacknowledged. Nearly halfway into President Trump’s first term—which some people hope and others fear will be his only one—the contours of his code have become pretty clear.

Mr. Trump has a consistent way of judging people. Strong is good, weak is bad. Big is impressive, small is defective: “Little Marco.” Winners are admirable, while losers are contemptible. A corollary is that there is neither dishonorable victory nor honorable defeat, which is why Mr. Trump poured scorn during his candidacy on John McCain for having been captured—never mind McCain’s heroic conduct as a prisoner of war.

Individuals are either attractive or unattractive. If they don’t look good, it doesn’t much matter what they say or do. Appearance is reality: Plato’s Cave inverted. This is why Mr. Trump’s TV stardom mattered more than his checkered business career.

Finally, people are either loyal or disloyal. Loyalty in this case means their willingness to defend Mr. Trump, whatever the cost to their own interests or reputation. In this vein, Mr. Trump favorably compared former Attorney General Eric Holder’s unswerving support for President Obama with Jeff Sessions’s decision to recuse himself from the Russia probe.

This brings us to the next feature of Mr. Trump’s personal code—his distinctive understanding of how the world works. Here’s how it goes.

With the possible exception of family, all relationships are at bottom transactional. Every man has a price, and so does every woman.

There’s money, and then everything else. Money and morals are unrelated. Even if a Saudi leader ordered the assassination and dismemberment of a prominent dissident, this is no reason to halt arms sales to the monarchy. If American firms don’t get the contracts, someone else will. Why should we be chumps? If promoting democracy or simple decency costs money, what’s the point?

The core of human existence is competition, not cooperation. The world is zero-sum: If I win, someone else must lose. I can either bend another to my will or yield to his.

The division between friends and enemies is fundamental. We should do as much good as we can to our friends, and as much harm to our enemies.

This brings us to President Trump’s handbook of tactics we should employ to achieve our goals:

Rule 1: The end always justifies the means. Asked whether he had spoken disrespectfully about Christine Blasey Ford, he said, “I’m not going to get into it, because we won. It doesn’t matter; we won.” Case closed.

Rule 2: No matter the truth of accusations against you, deny everything. Bob Woodward’s recent book quotes Mr. Trump counseling a friend who had privately confessed to sexual-misconduct charges against him. “You’ve got to deny, deny, deny, and push back hard on these women,” says Mr. Trump. “If you admit to anything and any culpability, then you’re dead.” The corollary to Rule 2 is that the best defense is a good offense. As the president told his friend, “You’ve got to be strong. You’ve got to be aggressive. Never admit.”

Rule 3: Responding to criticism on its merits is pointless. Instead, challenge the motives and character of your critics. Their criticism isn’t sincere anyway: It’s all politics, the unending quest for dominance. If ridicule works, use it, even if it means caricaturing your adversaries by reducing them to their weakest trait. If Jeb Bush is “low energy,” who cares what he thinks about immigration?

Rule 4: To win, you must arouse your supporters, and deepening divisions is the surest way to do it. Even if compromise could solve important problems, reject it whenever it threatens to reduce the fervor of your base. No gain in the public good is important enough to justify the loss of power.

Rule 5: It is wonderful to be loved, but if you must choose, it is better to be feared than loved. The desire for love puts you at the mercy of those who can withhold it; creating fear puts you on offense. You cannot control love, but you can control fear. And this is the ultimate question of politics, indeed, of all human life: Who’s in control?

Defenders of President Trump’s code of conduct will point to what they see as its unsentimental realism. His maxims are the terms of effectiveness in the world as it is, not as we would like it to be. They may not be pretty, but they work. Politics is not like figure skating. You get no points for style. You either get your way or you don’t. Nothing else matters.

Critics of Mr. Trump’s code—I’m one of them—view the distinction between permissible and forbidden means as essential to constitutional democracy, and to all decent politics. What Mr. Trump’s supporters see as the restoration of national greatness, his critics see as the acceleration of national decline.

This, to no small extent, is what next month’s elections are really about.
