The American Association for Nude Recreation has produced an excellent article on the ethics of naturism.
Naturists have always been at the forefront of the ethical debates:
Respect, both for people and our environment.
Equality.
Personal Freedom and Autonomy.
The following brief quote from the article sums up the philosophy, but we urge you to click the link and read the whole article.
The ethical values inherent in naturism provide a profound commentary on how we can live more harmoniously with ourselves, with others, and with the natural world. While often misunderstood, a deeper exploration into naturist communities reveals a lifestyle that is ethically rich and philosophically profound. As we look towards building a better future, the lessons and values derived from naturism deserve our attention and respect.
