Auguste Comte: A General View of Positivism (1856)

“The law is this: that each of our leading conceptions, each branch of our knowledge, passes successively through three different theoretical conditions: the Theological, or fictitious; the Metaphysical, or abstract; and the Scientific, or positive….the phenomena of human life… are yet equally subject to invariable laws; laws which form the principal objects of Positive speculation… [Positivism] rests at every point upon the unchangeable Order of the world. The right understanding of this order is the principal subject of our thoughts; its preponderating influence determines the general course of our feelings; its gradual improvement is the constant object of our actions.”
