Page "Is–ought problem" Paragraph 8

Ethical naturalists contend that moral truths exist, and that their truth value relates to facts about physical reality.

Many modern naturalistic philosophers see no impenetrable barrier in deriving " ought " from " is ", believing it can be done whenever we analyze goal-directed behavior.

They suggest that a statement of the form " In order for agent A to achieve goal B, A reasonably ought to do C " exhibits no category error and may be factually verified or refuted.

" Ought " s exist, then, in light of the existence of goals.
