What is natural
/A favourite lecturer of mine once asked why we are surprised about anything we find humans doing - because anything we find them doing is only natural.
It is culture that inhibits, applying imaginary boundaries to what is natural. Sometimes this is beneficial, sometimes this is harmful, often what is perceived as beneficial and harmful will change over time.
We have basic biological needs and constraints. Anything outside of this we have the ability to create, shape and give meaning to.
