Existence is subject-predicate. When Descartes said, “I think therefore I exist (Je pense donc je suis)”, “think” was predicate. Predicate is evidence of existence. Predicate is more than evidence; it is existence in time. In the structure of a sentence, we can separate the subject from the predicate. This is an artificial separation. In reality, the subject (the “amness”) is always “ising” – and so am I.
