Ludwig von Mises 
"The a priori categories are the endowment that enables man to attain all that is specifically human and distinguishes him from all other beings. Their analysis is analysis of the human condition, the role man plays in the universe. They are the force that enables man to create and to produce all that is called human civilization." 

As Mises's final book, the first edition (Van Nostrand) appeared in 1962. The Mises Institute would like to thank Bettina Bien Greaves, who gave her permission for this online edition. This edition is also available in PDf and hard copy. The text edition follows:
