It is natural to think that history (the scholarly discipline not the process) is the art of writing true sentences about human beings in the past tense. There are no doubt historians who would call that sort of description simple-minded, but I think laypeople tacitly accept that such an art is possible. Consider the possibility, however, that human beings can't (technically) be "objects", i.e., that there can't be "true sentences about" them. When writing about people, we must write just sentences in the future tense. That is, all our judgments about people are about what will happen (or, more precisely, what we would have happen), not was has happened.
