I have loyally and candidly maintained my thesis on scientific grounds;
I have always recognized the partial truths of the theories of our
opponents, and I have not ignored the glorious achievements of the
bourgeoisie and bourgeois science since the outbreak of the French
Revolution. The disappearance of the bourgeois class and science,
which, at their advent marked the disappearance of the hieratic and
aristocratic classes and science, will result in the triumph of social
justice for all mankind, without distinction of classes, and in the
triumph of truth carried to its ultimate consequences.

The appendix contains my replies to a letter of Herbert Spencer and to
an anti-socialist book of M. Garofalo. It shows the present state of
social science, and of the struggle between ultra-conservative
orthodoxy, which is blinded to the sad truths of contemporary life by
its traditional syllogisms and innovating heterodoxy which is ever
becoming more marked among the learned, as well as strengthening its
hold upon the collective intelligence.
