XIV. ‘There,’ I said, ‘let all this serve for so many dykes or barriers against those bitter and aggressive assailants! Now, let us go back, and pick up the end of the thread in this dark place with its windings and wanderings; I mean our argument about the God. Let us guide ourselves with quiet caution towards what is likely and reasonable, since certainty and truth are beyond us, even as to our own actions. For instance, why do we order the children of persons who have died of consumption [Sidenote: E] or dropsy to sit with both feet dipped into water until the corpse is consumed? The idea seems to be that, if this is done, the disease does not shift its seat or approach them. Or again, why is it that, if one goat have taken the herb eryngium[234] into her mouth, the whole flock halts until the goatherd comes and takes it out? And there are other occult properties, with ways, whether of contact or of dissemination, by which they pass, with incredible speed and over incredible intervals, through one to another. Yet we find intervals of time wonderful, but [Sidenote: F] not those of place; although it is really more wonderful that a disease which began in Aethiopia[235] infected Athens, where Pericles died and Thucydides took it, than that, when Delphians and Sybarites had been wicked, the punishment circled round to attack their children. There is correspondence of forces from last to first, and there are connecting links, the cause of which, unknown, it may be, to us, produces in silence its proper effect.[236]
