# Four Unities

What are the Four Unities? Sorry to be vague.

Time
Title
Interest
Possession
4 things that are required for a Joint Tenancy

(edit…

Time - both prospective joint tenants have to acquire their interest in the property at the same time
Title - both prospective joint tenants have to have their interest granted to them by the same instrument
Interest - both prospective joint tenants have to have the same type of interest (one can’t have a life estate and the other a fee simple)
Possession - both prospective JTs have to have equal right to possesion of the property

In drama, there are only three unities: Action, Place, and Time.

Gas
Electricity
Garbage
Water

I’m sorry, I meant the three unities. Does anyone know who first spoke of them in drama?

Aristotle.

Whereas in math, the four unities are 1, -1, i, and -i.

You really need to be un-vague in questions, if you want a relevant answer.

Sorry to be so snarky, but your question is vague. :dubious:

Since the question seems to have been answered adequately, I’m going to chime in with the George Carlin answer.

Armpits, asshole, crotch, and teeth.

I commend your efforts in snarking the well-deserving OP, but surely those are actually the fourth roots of unity (i.e., of 1)…

Alternatively, those are the four “units” in the ring of Gaussian integers. But I don’t think anyone would ever call them “unities” instead.

So, you gave essentially two words to go on in your OP, and one turned out to be wrong? Brevity is the soul of wit and all that, but really.

As Contrapuntal said, you are referring to the idea of Classical Unities generally attributed to Aristotle, in the sense that he was the first writer (as far as we know) to set them down as advisable principles for a dramatist or poet to follow.

Just for interest, there are still writers who experiment with the challenge of complying with these principles. My favourite example in popular culture is the episode of ‘Friends’ entitled ‘The One Where No-One’s Ready’ (Season 3, episode 2, but I only know that because I just looked it up). It all takes place in one place, in real time, and concerns one principle motive (Ross’s desire to go to the Museum banquet). Another good pop culture example would be Hitchcock’s thriller ‘Rope’.
