"Beyond the limits of the most comprehensive actual society are living creatures whom our moral impulse bids us to include within our system of organized, reciprocal relations, although up to the present we have found this impossible to achieve. Nevertheless, we can at least reach out to help them when in distress, as by rescuing them from the pools and pits into which they sometimes fall, feeding them when hungry as far as our means allow, perhaps at times curing their wounds. Such charity is the truest sort, because we can never expect any extrinsic recompense nor even an indirect economic advantage from it. When we contemplate the vast amount of mutilation, suffering, and death which hourly occurs among the living creatures on this planet, and the complex relations among them which make it impossible for us to help one of them without perhaps indirectly injuring another, we sometimes suspect that our most devoted effort on behalf of nonhuman creatures is scarcely more than a gesture. Yet it is a gesture which symbolizes the comprehensive society that we aspire to create."
