What does King of Swords mean in love?

A rational, principled, sometimes emotionally reserved partner.

He is fair, consistent and safe to disagree with, and he can be hard to reach. Feelings are not his instrument, and a partner who needs them expressed will spend a long time inferring.

Reversed, somebody who argues you out of your own feelings. That is worth naming plainly: being reasoned into accepting that you do not feel what you feel is a real and disorienting experience, and it does not require anybody to intend it.

As somebody's feelings, he reads as considered and principled. Whatever is felt has been examined, and it will be expressed as a conclusion rather than as an outpouring.

Impartial judgement and clear reasoning. Set the standard and hold to it.

Excellent for legal, ethical and strategic decisions, and for any situation that has been decided several times on the basis of who was most persuasive that day.

In an advice position he says decide on the principle rather than on who is asking, and then apply it to yourself as well. The second half is what separates him from somebody merely inflexible.

Cold, controlling, using intellect as a weapon. Judgement without compassion.

Also, and this is the sharper reading, reasoning bent to justify a conclusion already reached. He is clever enough to construct an argument for anything, and the reversal is where that capacity is pointed at his own preferences.

It is very difficult to challenge from outside, because every individual step of the argument is sound.

Upright: authority, impartial judgement, ethics, clarity, strategy

Reversed: coldness, manipulation, harsh judgement, rationalising

• What principle should decide this, independent of who benefits?
• Am I reasoning toward the truth or toward what I already want?
