John Locke discussed natural rights which are our government's emphasis on individual rights. His writing discussing this topic is titled, "Common Sense," as he believed these natural rights (unalienable rights) are rights that cannot be taken away by the government. To Locke, these rights were common sense. Hope this helps! :)
