Read the quote from John Locke.

"...no one [or government] ought to harm another in his life, health, liberty, or possessions...and may not, unless it to be to do justice on an offiender, take away, or impair the life, or what tends to the preservation of the life, the liberty, health, limb or goods of another..."

According to the quote, Locke believed that government's main purpose is to ___________ people's human rights.
