《Tetrabiblos》That Prescience Is UsefulClaudius Ptolemy（Ashmand 英譯 1822）
But, since the foreknowledge of particular circumstances, although it may not wholly claim infallibility, seems yet so far practicable as to merit consideration, so the precaution it affords, in particular circumstances, deserves in like manner to be attended to; and, if it be not of universal advantage, but useful in few instances only, it is still most worthy of estimation, and to be considered of no moderate value.
