What is science? Is it uniquely equipped to deliver universal truths? Or is it one of many disciplines - art, literature, religion - that offer different forms of understanding? In The Meaning of Science, Tim Lewens offers a provocative introduction to the philosophy of science, showing us for example what physics teaches us about reality, what biology teaches us about human nature, and what cognitive science teaches us about human freedom. Drawing on the insights of towering figures like Karl Popper and Thomas Kuhn, Lewens shows how key questions in science matter, often in personal, practical and political ways.
