Aristotle’s theory of the four causes seems at first sight very easy to understand, but if you dig into the details, you will see its epochal consequences. It changed human mentality, and in doing so, it changed the course of history. The four causes, and in particular the final cause, can dramatically change your life for the better.
Aristotle adopted a systematic approach to studying the world. His theory of the four causes entails that, if you want to fully understand something, you should consider four distinct causes.
First, a material cause that pertains to the material substance that makes up an item or creature. For example, the material cause of a woolen suit is wool.
Second, a formal cause that relates to the object’s shape or structure. In the case of the woolen suit, the formal cause consists of a vest and a pair of pants. Their shape constitutes a suit, not a scarf, a raincoat, a shirt, or an overall.
Third, an efficient cause that is concerned with the agent or force responsible for making the object. It replies to the question “What brought the object into existence?” In the context of the suit, the efficient cause is the tailor who made it.

Fourth, a final cause that deals with the purpose. It answers the question, “Why does the object exist?” In the case of the suit, the final cause is to allow me to wear the suit for work, formal dinners, and other such occasions.
The theory of the four causes seems simple enough as a tool for analyzing reality, but as we’ll see now, it gets exceedingly complicated when it is coupled to social and political events. It is not exaggerated to affirm that Aristotle’s theory of causation has driven the intellectual discourse for twenty-five centuries.
