Opposite Signs and Why They Attract

Every sign in the zodiac has exactly one opposite: the sign sitting directly across the wheel from it, six places away in either direction and half a year away in the calendar. There are six such pairs. Aries with Libra, Taurus with Scorpio, Gemini with Sagittarius, Cancer with Capricorn, Leo with Aquarius, and Virgo with Pisces. Astrology calls that gap of 180 degrees an opposition, and unlike most gaps on the wheel it is read as a pull rather than a problem.

The six pairs and what each one splits

Each pair takes one ordinary human requirement, cuts it in half and gives one half to each sign. That is the whole design, and it is quicker to see in a list than to argue in the abstract.

• Aries and Libra. Doing it alone against doing it together. One trusts the first instinct; the other will not move until both people have been asked.
• Taurus and Scorpio. What is mine against what is ours. Comfort, ownership and steadiness on one side, and everything that gets shared, risked or handed over on the other.
• Gemini and Sagittarius. Facts against meaning. One collects and compares; the other wants to know what the whole pile adds up to.
• Cancer and Capricorn. Home against the outside world. Who gets looked after in private, and what gets built where everyone can see it.
• Leo and Aquarius. The individual against the group. Warmth aimed at a few named people, or principle applied to everybody equally.
• Virgo and Pisces. The part against the whole. One improves the detail in front of it; the other refuses to cut the picture up.

None of those six lines sets a virtue against a vice. Each is a reasonable position facing another reasonable position, which is why disagreements along an axis run for years and why neither end ever quite wins.

Opposite is not the same as incompatible

Six signs apart always lands on the same quality, the grouping that sorts signs by whether they prefer to begin something, hold it steady or change it as it goes. Aries and Libra are both cardinal, the ones that start. Taurus and Scorpio are both fixed. Gemini and Sagittarius are both mutable, the ones that adjust. So a pair of opposites moves at the same speed and enjoys the same stage of a job. They rarely disagree about pace. They disagree about direction.

The elements fall the same way. Fire always faces air and earth always faces water, so no pair of opposites puts fire against water or earth against air. Those two combinations, fire with air and earth with water, are precisely the ones traditional astrology already rates as comfortable. An opposition is built out of ingredients that were never going to repel each other.

The old planetary rulerships, which hand each sign a planet as its manager, repeat the pattern once more. Aries and Libra set Mars against Venus, and Taurus and Scorpio use those same two the other way round. Cancer and Capricorn put the Moon opposite Saturn. Both Mercury signs, Gemini and Virgo, face a Jupiter sign, Sagittarius and Pisces respectively.

What the attraction is supposed to be

The traditional claim is blunt: the thing you keep leaving out is standing across from you. Every sign is described as liable to overdo its own half of the axis, and the correction is written into the sign it faces. A Sagittarius certain of the big picture and vague on the specifics is looking at Gemini. A Virgo buried in specifics with no sense of the whole is looking at Pisces.

Read as a relationship, that is fit rather than likeness. Two people who see a situation identically agree pleasantly and learn nothing from it. Two people on the same axis want the same outcome and cannot agree on the route, so each keeps forcing the other to account for something they would have skipped. That is the mechanism the old phrase about opposites is pointing at, in astrology or anywhere else.

The same geometry appears in the sky every month, since the Moon only shows a complete disc once it has travelled round to the sign facing whichever one the Sun is crossing. A full moon is an opposition you can go outside and look at.

The pull and the irritation are one mechanism

Ask people which sign they cannot stand and a striking number name their own opposite. That is not a contradiction of the attraction, it is the same thing viewed from the other side. Astrologers use the word projection for it: the half of the axis you will not do yourself gets handed to somebody else, and then you dislike them for doing it.

The accusations are remarkably consistent. A Capricorn who never lets himself need anything finds Cancer clingy. A Cancer who has never once asked for credit finds Capricorn cold and calculating. An Aquarius calls Leo self-absorbed; a Leo calls Aquarius chilly and theoretical. Each complaint is well aimed, and each is aimed at the missing half.

This is why the opposition is classed as a tense angle rather than an easy one. Tense here means it demands work and produces something. The comfortable angles demand nothing and, in the traditional reading, produce about as much.

Oppositions outside the sun signs

Everything above uses sun signs, because that is the part most people know about themselves. The opposition is really an angle between any two points in a birth chart, the map of the sky drawn for your exact birth details. Any two bodies in it standing 180 degrees apart are in opposition, and that has nothing to do with the sign you give people at a party.

Every chart also carries a built-in opposite. The point across from the ascendant, the sign lifting above the eastern skyline as you arrived, is called the descendant, and tradition assigns it to partnership. A chart rising in Taurus has Scorpio there. People who know their birth time often find that axis a sharper account of what they look for in others than their sun sign manages.

When two charts are laid against each other, a practice known as synastry, oppositions between them turn up constantly in couples who lasted and just as constantly in couples who fought for a decade and stopped. The angle says a subject matters to both. It says nothing about how they handled it.

How much weight to give it

On its own, not much. Attempts to find a sun sign pattern hiding in large sets of marriage records have not turned one up, and any system that sorts everybody alive into twelve boxes will be right by accident a good deal of the time. Two people are not two labels.

Where the axis earns its keep is as a question. When an argument keeps returning in the same shape, it is worth asking which end of a single shared need each of you is defending, because that turns one person being wrong into one requirement split in two. The zodiac did not discover that pattern. It gave six versions of it names and put them in a circle.
