The fourth arcanum gives support and order. Such a person holds a structure well: they understand who is responsible for what, and they cannot stand vagueness.
They come to need clear rules early — in childhood as well. Where the boundaries are marked out plainly and in the same way for everyone, they are calm; where the arrangements keep shifting, they are anxious and stubborn.
The strength is reliability. The fourth arcanum can be relied on, and it knows that about itself.
The weakness is inflexibility. Admitting that an order has gone out of date is harder for them than building a new one from scratch, and they take an argument as a test of their solidity rather than as an exchange of reasons.
