Guardians are necessary for children and abnormal adults, because they cannot make responsible choices for themselves.

Libertarians argue that no normal adult has the right to impose choices on other normal adults, except in abnormal circumstances, such as when one person finds another unconscious and administers medical assistance or calls an ambulance.

It is precisely because neither individuals nor small groups can be fully self-sufficient that cooperation is necessary to human survival and flourishing.

What libertarians assert is simply that differences among normal adults do not imply different fundamental rights.

Real vision demands that we make tough choices. Real vision is responsible and it is paid for.

As adults feign disinterest in science - children can grab hold of it to distinguish themselves.
