The Purpose of Praxeology

Every single action is strictly limited in its immediate consequences. The road to the performance of great things must always lead through the performance of partial tasks. A man never chooses between gold and iron in general, but always only between a definite quantity of gold and a definite quantities of iron. What counts for praxeology is the fact that the only method to achieve greater task is to build from the foundations, step by step, part by part.
