Truly, in living this life no man is self-sufficient, or adequately endowed by nature. For when he is born, destitute of all help, naked and defenceless…he is cast forth into the hardships of this life, not able by his own efforts to reach a maternal breast, nor to endure the harshness of his condition… Nor in his adulthood is he able…to provide by his own energies all the requirements of life… As long as he remains isolated and does not mingle in the society of men, he cannot live at all comfortably and well while lacking so many necessary and useful things. An aid and remedy for this state of affairs is offered him in symbiotic life. He is led, and almost impelled, to embrace it if he wants to live comfortably and well, even if he merely wants to live.
