Economics sets the objective parameters of the choices we make. It
explains and estimates the sacrifices we make when we chose to pursue
one goal over another. Philosophy sets the subjective parameters of
choice and explains why each goal deserves to be on our "do list,"
and whether the sacrifices involved are worth making.
