What did john locke believe the human mind to be at birth and what were the practical implications his theory?

Explanation:

John Locke was an empiricist. That means he believed in experience as the source of all knowledge.  The mind, in his view, began as a "tabula rasa." That's Latin for "blank slate" -- or like an empty chalkboard waiting to be written on.  Through the experiences we have, we accumulate knowledge one bit at a time and combine those elements of knowledge into learning.

Locke also applied this sort of thinking in his thoughts about government and society. Experience guides us as human beings toward understanding what works best (and what doesn't work) in the formation of societies.  This includes choosing to form governments that will protect the rights and freedoms of the governed.

Lock believed humans are born naturally reasonable
