Of two equivalent theories or explanations, all other things being equal, the simpler one is to be preferred.

No more things should be presumed to exist than are absolutely necessary.

For nothing ought to be posited without a reason given, unless it is self-evident (literally, known through itself) or known by experience or proved by the authority of Sacred Scripture.

Intuitive cognition of a thing is cognition that enables us to know whether the thing exists or does not exist, in such a way that, if the thing exists, then the intellect immediately judges that it exists and evidently knows that it exists, unless the judgment happens to be impeded through the imperfection of this cognition.

First it must be known that only a spoken word or a conventional sign is an equivocal or univocal term; therefore a mental contentor concept is, strictly speaking, neither equivocal nor univocal.
