Difference between Teleology and Deontology? 

Deontology and Teleology are both terms used in philosophy. Deontology is the study of duty. It is a part of a philosophy that covers ethics and explains aspects such as what is forbidden and what is permitted.

Teleology stands for purpose or result and logos, which means study or science.It is focused on the purpose instead of the causes by which those purposes originate.
