《Tetrabiblos》That Prescience Is UsefulClaudius Ptolemy（Ashmand 英譯 1822）
The same order and consequence exist in all cases, whether the events have a general or only a particular operation; and it may therefore well be demanded, why prescience is believed to be possible as far as it regards general events, and why it is allowed to be serviceable in preparing for their approach; while in particular instances its power and use are altogether denied.
