"The fundamental theory of liberty... excludes any general power of the State to standardize its children by forcing them to accept instruction from public teachers only."

"The child is not the mere creature of the State; those who nurture him and direct his destiny have the right, coupled with the high duty, to recognize and prepare him for additional obligations."

Pierce v. Society of Sisters (1925).

That's a quote that always jumps out at my when I start into the right of privacy materials in Constitutional Law II, which is what I'm doing this afternoon. The state of Oregon required parents to send their children to public school, and the Supreme Court said they had a substantive due process right to pick private school.
