ABSTRACT
This Appendix fulfills the promise that I made, in 1851, when I commenced the treatise now completed, of reproducing all my early essays on social philosophy. Collected from periodicals long since forgotten, they may assist students disposed to follow my own course of philosophical development in their efforts to master positivism. But their publication is more especially intended to demonstrate the perfect harmony that exists between my youthful efforts and my matured conceptions.
