The most important source of conflict is the unwarranted idea that language maps on to “reality” – and that we can test the degree to which it does by the correspondence between our ideas and the organization of the “real world.” In that frame, differences in perception devolve to who is right and who is wrong, and intellectual or actual fighting is not far away. But this idea about “truth” is unjustified and wrong. What Donald Hoffman has done in this book is to show that our common sense understanding that our sensory and perceptual systems evolved to correspond to the world is a delusion. And when you appreciate that evolutionary epistemology does not support delusion, then you are much more able to cut yourself loose from unnecessary ontological assumptions and can instead focus on how to use your life to interact with this one world in ways that are… show more.

Immanuel Kant is one of the most important figures in the history of philosophy – specifically regarding metaphysics – because he discovered the internal logic and organization for all of philosophical metaphysics. The book with which Kant accomplished that monumental feat is extremely difficult to read and understand. Therefore, Kant wrote an easier-to-read version, and that is the book that I am recommending: Philosophy of Material Nature. This book is highly affordable and readable.

The book that the Philosophy of Material Nature paraphrases is, of course, the Critique of Pure Reason. What all of these works show us is that philosophical metaphysics naturally divides into theological metaphysics, cosmological metaphysics, and psychological metaphysics. Kant’s achievement is standardly characterized as the articulation of philosophical metaphysics as a science. The general term for such a science is “transcendental philosophy.” Thus, the rest of the books in this recommendation list relate to… show more.

Polanyi, an eminent Hungarian Jewish chemist who spent his career at the University of Manchester, was the smarter brother of the more famous Karl Polanyi, the socialist economic historian. Michael (Mihály) shows in the book how science depends on ordinary, “personal” knowledge, as for example in riding a bicycle. He was a “liberal” in the European sense, unlike his brother, and saw the scientific community as analogous to a free market, and the free market as analogous to a scientific community.

In this book, one of the great philosophers of the first half of the 20th century sketches his take on two central philosophical tasks -- explaining what kinds of things exist in reality, and how they are related, and delineating what we can know and how we know it.  In so doing, Russell illustrates the new method of logical and linguistic analysis he used in The Philosophy of Logical Atomism (1918), to lay the foundations of an epistemological and metaphysical system rivaling the great systems of the past. A key transitional figure linking the history of the subject to contemporary concerns, he raised logic and language to central subjects of philosophical study in their own right, without losing sight of their relevance for more traditional philosophical quests.

This is a popular, reliable, wide-ranging introduction to metaphysics by two respected philosophers. It covers topics such as personal identity, fatalism, time, God, free will and determinism, possibility and necessity, and criticisms of metaphysics itself. It asks why there is something rather than nothing, and whether distinctions between good and evil and between right and wrong have any objective reality. Ted Sider is a leader of new developments in contemporary metaphysics.

I regard this book as perhaps the greatest book about the nature of science ever published. In it, Popper spells out his dramatic view that science proceeds by putting forward bold, imaginative guesses, which are then subjected to ferocious attempts at empirical refutation. When these conjectured theories are refuted, scientists are forced to think up a better conjectural theory–and that is how science makes progress.

In this book, Popper shows how this dramatic account of how science proceeds by a process of conjecture and refutation has implications for fields beyond science, such as philosophy, in that it implies that, whatever we are doing, our best hope of success in solving our problems is to consider possible solutions and subject them to ferocious criticism.

This is an accessible defence of the astonishing theory that there are infinitely many possible worlds other than our own, with just as much flesh-and-blood reality; they are systems of space and time disconnected from ours. Many of those worlds contain almost exact counterparts of you. Lewis argues that his theory is much less alien to common sense than it seems, and that it provides the best explanation of many puzzling matters, such as the distinction between what is possible and what is impossible. Although few philosophers accept Lewis’s theory, it is extraordinarily difficult to disprove. David Lewis was the most influential metaphysician of the past half-century.
