An ethical system which places the welfare of the human race as the exclusive goal of human effort and the basic standard of conduct.
It rejects, commonly, any consideration of God, of God's Will expressed in Revelation, and the immortality of the soul.
In place of these external values, it considers the welfare of the continuing human race as the only abiding good, and hence the only rational object of will and endeavor.
While this philosophy inculcates much good, it is fundamentally wrong in its view of God and man, and often teaches positive wrong, e.g., negative eugenics.
The Christian duty of charity and justice includes all the best elements of this system, and avoids its errors.
