Volume 2: Unfashionable Observations, translated by Richard T. Gray, was published in 1995; Volume 3: Human, All Too Human (I), translated by Gary Handwerk, was published in 1997. The edition is a new English translation, by various hands, of the celebrated Colli-Montinari edition, which has been acclaimed as one of the most important works of scholarship in the humanities in the last half century.The present volume provides for the first time English translations of all of Nietzsche's unpublished notebooks from the summer of 1872 to the end of 1874. The major works published in this period were the first three Unfashionable Observations: "David Strauss the Confessor and the Writer," "On the Utility and Liability of History for Life," and "Schopenhauer as Educator." Translations of the preliminary notes for these pieces are coordinated with the translations of the published texts printed in Volume 2: Unfashionable Observations.The content of these notebooks goes far beyond the notes and plans for published and unpublished Unfashionable Observations, encompassing numerous sketches related to Nietzsche's major philological project from this period, a book on the pre-Platonic Greek philosophers. The ideas that emerged from Nietzsche's deliberations on these early Greek thinkers are absolutely central to his thought from this period and contribute in significant ways to the development of several of his major themes: the role of the philosopher vis-à-vis his age and the surrounding culture; the relationships among philosophy, art, and culture; the metaphorical nature of language and its relationship to knowledge; the unmasking of the modern drive for absolute "truth" as a palliative against the horror of existence; and Nietzsche's "unfashionable" attack on modern science and modern culture, especially on the Germany of the Bismarck Reich. These notebooks represent important transitional documents in Nietzsche's intellectual development, marking, among other things, the shift away from philological studies toward unabashed cultural criticism.

    His fundamental work, The Methods of Ethics (first edition 1874, seventh and last edition 1907, here reprinted), is the clearest and most accessible formulation of what we may call 'the classical utilitarian doctorine.' This classical doctrine holds that the ultimate moral end of social and individual action is the greatest net sum of the happiness of all sentient beings. Happinesss is specified (as positive or negative) by the net balance of pleasure over pain, or, as Sidgwick preferred to say, as the net balance of agreeable over disagreeable consciousness. . . .

    He was trained in medicine at Heidelberg and became a physiologist, but he soon began collecting data on behavior as well as on structure. In 1873 he published his Principles on Physiological Psychology. This book of 870 pages eventually became three volumes totaling 2,317 pages in the sixth edition of 1908–1911. These six editions were, in effect, the history of experimental psychology's first 40 years. From 1875 until 1910, Wundt taught at Leipzig. There he established the world's first psychology laboratory (1875) and founded its first journal of psychology (1881). Wundt's laboratory research concentrated on two topics:(1) sensation and perception and (2) the measurement of reaction times. To study these, he used the technique of introspection, in which human subjects reported exactly what they experienced upon being presented with a stimulus (e.g., light). Despite the primitive conditions of this early laboratory remarkably little that Wundt did has been totally rejected, and the research he conducted created the basic character of modern experimental psychology.
