All she can do is fatten and divide; She cannot even read, or sew, or cook.... The Worm can crawl--but has no eyes to look: The Jelly-fish can swim--but lacks a bride: The Fly’s a very Ass personified: And speech is absent even from the Rook. The Ant herself cannot philosophize-- While Man does that, and sees, and keeps a wife, And flies, and talks, and is extremely wise.... Will our Philosophy to later Life Seem but a crudeness of the planet’s youth, Our Wisdom but a parasite of Truth? PHILOSOPHIC ANTS: A BIOLOGIC FANTASY[41] “Incomprehensibility; that’s what I say.”--LEWIS CARROLL (_amended_). According to a recent study by Mr. Shapley (Proc. Nat. Acad. Sci., Philadelphia, vol. vi, p. 204), the normal rate of progression of ants--or at least of the species of ant which he studied--is a function of temperature. For each rise of ten degrees centigrade, the ants go about double as fast. So complete is the dependence that the ants may be employed as a thermometer, measurement of their rate of locomotion giving the temperature to within one degree centigrade. * * * * * * * The simple consequence--easy of apprehension by us, but infinite puzzlement to ants--is that on a warm day an ant will get through a task four or five times as heavy as she will on a cold one. She does more, thinks more, lives more: more Bergsonian duration is hers.
