Syn. To be, Exist.
The verb to be, except in a few rare cases, like that of Shakespeare's “To be, or not to be”, is used simply as a copula, to connect a subject with its predicate; as, man is mortal; the soul is immortal. The verb to exist is never properly used as a mere copula, but points to things that stand forth, or have a substantive being; as, when the soul is freed from all corporeal alliance, then it truly exists. It is not, therefore, properly synonymous with to be when used as a copula, though occasionally made so by some writers for the sake of variety; as in the phrase “there exists [is] no reason for laying new taxes.” We may, indeed, say, “a friendship has long existed between them,” instead of saying, “there has long been a friendship between them;” but in this case, exist is not a mere copula. It is used in its appropriate sense to mark the friendship as having been long in existence.
