"Plato use the expression "techne tou biou"...

 “Plato used the expression techne tou biou, which means “the craft of life.”  When techne is defined with sufficient depth, it refers not just to mechanical skills and instruments but to all kinds of artful managing and careful shaping…we can say that care of the soul requires a special crafting of life itself, with an artist’s sensitivity to the way things are done.  Soul doesn’t pour into life automatically.  It requires our skill and attention.”
