When, as so often happens, people say that truth should be simple, this is due to indolence and a dislike of having to wrestle with many concepts; but the greatest truths can be apprehended only when the spiritual faculties are exerted to their utmost capacity. If considerable efforts are needed to describe a machine, it is surely unreasonable to demand that the greatest truths should also be the simplest! Truth is inevitably complicated, and the most strenuous efforts must be made if it is desired to acquire some understanding of the truths relating to the Events of Palestine. Nobody should lend himself to the objection that the facts are unduly complicated; they are complicated because here we have to do with the greatest of all happenings in the evolution of the Earth.
