Consider Her Ways by Frederick Philip Grove

Perhaps there are more ants on this globe that live, at least in part, symbiotically or in a state of mutualistic co-operation with certain other beings, such as aphids, coccids, membracids, and fulgorids, or with the caterpillars of Lycenid butterflies or blues than in any other way. Some of them, keeping membracids, are well known in our own country and have been minutely studied in the past. Excellent monoscents are available to the student.

If, then, I shall consider one or two of them once more, there are three reasons for doing so. In the first place, this record is to be a bird's-eye view of the whole of antdom. In the second place, certain ants keeping cattle have reached a degree of civilization second only to our own; and since they do not reach that high level in our own country, they demand particular notice here. In the third place, it has been rumoured that man also keeps cattle; and from that fact it has been inferred by certain bold speculators that he must have reached a social and intellectual stage little below that of certain ants, though not the most highly developed kinds. It will be seen how dangerous it is to pursue external analogies into the realm of ultimate values, and how exceedingly difficult for any investigator, to rid herself of myrmecomorphic or myrmecocentric fallacies when dealing with the lower animals.
