But such speculations may well be avoided. Let not the possibility of general annihilation blur our perception of the task before us; above all, let us not count on the miraculous aid of chance. Hitherto, the promises of our imagination notwithstanding, we have always been left to ourselves, to our own resources. It is to our humblest efforts that every useful, enduring achievement of this earth is due. It is open to us, if we choose, to await the better or worse that may follow some alien accident, but on condition that such expectation shall not hinder our human task. Here again do the bees, as Nature always, provide a most excellent lesson. In the hive there has truly been prodigious intervention. The bees are in the hands of a power capable of annihilating or modifying their race, of transforming their destinies; the bees' thraldom is far more definite than our own. Therefore none the less do they perform their profound and primitive duty. And, among them, it is precisely those whose obedience to duty is most complete who are able most fully to profit by the supernatural intervention that to-day has raised the destiny of their species. And indeed, to discover the unconquerable duty of a being is less difficult than one imagines. It is ever to be read in the distinguishing organs, whereto the others are all subordinate. And just as it is written in the tongue, the stomach, and mouth of the bee that it must make honey, so is it written in our eyes, our ears, our nerves, our marrow, in every lobe of our head, that we must make cerebral substance; nor is there need that we should divine the purpose this substance shall serve. The bees know not whether they will eat the honey they harvest, as we know not who it is shall reap the profit of the cerebral substance we shall have formed, or of the intelligent fluid that issues therefrom and spreads over the universe, perishing when our life ceases or persisting after our death. As they go from flower to flower collecting more honey than themselves and their offspring can need, let us go from reality to reality seeking food for the incomprehensible flame, and thus, certain of having fulfilled our organic duty, preparing ourselves for whatever befall. Let us nourish this flame on our feelings and passions, on all that we see and think, that we hear and touch, on its own essence, which is the idea it derives from the discoveries, experience and observation that result from its every movement. A time then will come when all things will turn so naturally to good in a spirit that has given itself to the loyal desire of this simple human duty, that the very suspicion of the possible aimlessness of its exhausting effort will only render the duty the clearer, will only add more purity, power, disinterestedness, and freedom to the ardour wherewith it still seeks.
