The History of the Siege of Lisbon

CERTAIN AUTHORS, perhaps out of conviction or an attitude of mind not much given to patient investigation, hate having to acknowledge that the relationship between what we call cause and what we subsequently describe as the effect is not always linear and explicit. They allege, and with some justification, that ever since the world began, although we may have no way of knowing when it began, there has never been an effect without a cause, and every cause, whether because pre-ordained or by some simple mechanism, has brought about and will go on bringing about some effect or other, which, let it be said, is produced instantly, although the transition from cause to effect may have escaped the observer or only come to be more or less reconstituted much later.

Going further, somewhat rashly, these authors argue that all the visible and recognisable causes have already produced their effects, and that now we need only wait for them to manifest themselves, and they also insist that all effects, whether manifest or about to be made manifest, have their inevitable causality, although our manifold limitations may have prevented us from identifying it in terms of establishing the respective relationship, not always linear or explicit, as we said at the outset.
