In logic nothing is accidental:

if a thing can occur in a state of affairs,

the possibility of the state of affairs must be written

into the thing itself.

It would seem to be a sort of accident,

if it turned out that situation would fit a thing

that could already exist entirely on its own.

If things can occur in states of affairs, this possibility

must be in them from the beginning.

Nothing in the province of logic can be merely possible.

Things are independent in so far as they can occur

in all possible situations,

but this form of independence is a form of connection

with states of affairs,

a form of dependence.
