ABSTRACT
A serious book, written with great diligence. Mises eschews the childish superior airs that to my mind spoil so many works by otherwise gifted writers these days; quite the contrary, he is always anxious to pay due respect to the ideas of his predecessors and to make them the foundation for his own thought, in order to press on further in their footsteps — and this is undoubtedly the mark of all truly promising research.
