C.S. Lewis called the universal moral law “the Tao” in The Abolition of Man.
In the 1943 book, Lewis uses Tao as a broad term for an objective order of value recognized, in varied forms, across cultures and traditions. He argues that education should not merely train students to manipulate facts or express preferences; it should also cultivate proper responses to genuine human values.
Lewis borrowed the Chinese term Tao, traditionally associated with “the Way,” for this philosophical purpose. His use is not a claim that the book is simply a study of Taoism. It is a comparative term within his argument about moral objectivity.
The book’s Tao is therefore not the same as Logos, a Greek term with different philosophical and theological uses.
