In Walking, Henry David Thoreau talks about the importance of nature to mankind, and how people cannot survive without nature, physically, mentally, and spiritually, yet we seem to be spending more and more time entrenched by society. For Thoreau walking is a self-reflective spiritual act that occurs only when you are away from society, that allows you to learn about who you are, and find other aspects of yourself that have been chipped away by society. This new edition of Thoreau's classic work includes annotations and a biographical essay.

George Berkeley's investigation of human epistemology remains one of the most respected of its time - this edition contains the treatise in full, complete with the author's preface. One of Berkeley's most important beliefs was that of immaterialism. The meaning being that nothing material exists unless it is perceived by something or someone. Distinct from solipsism - the belief that only the self exists - Berkeley's view is that material items are ideas formed by distinct conscious minds; the concept of reality being simply the summation of shared ideas rather than physical objects fascinated philosophers of the era. Much of Berkeley's philosophy is framed by then-new discoveries in the field of physics. The concepts of color and light thus have a frequent bearing on the overall thesis; disagreeing with Isaac Newton on the subject of space, it was later that Berkeley's contrarian opinions on matters such as calculus and free-thinking gained him further renown.

In explicit form, Kant does not speak that much about values or goods. The reason for this is obvious: the concepts of 'values' and 'goods' are part of the eudaimonistic tradition, and he famously criticizes eudaimonism for its flawed 'material' approach to ethics. But he uses, on several occasions, the traditional teleological language of goods and values. Especially in the Groundwork and the Critique of Practical Reason, Kant develops crucial points on this conceptual basis. Furthermore, he implicitly discusses issues of conditional and unconditional values, subjective and objective values, aesthetic or economic values etc. In recent Kant scholarship, there has been a controversy on the question how moral and nonmoral values are related in Kant's account of human dignity. This leads to the more fundamental problem if Kant should be seen as a prescriptvist (antirealist) or as subscribing to a more objective rational agency account of goods. This issue and several further questions are addressed in this volume.
