The branch of Philosophy that covers the foundations, methods and assumptions in the field of science is Philosophy of Science. Here we strive to understand how science works, what makes the scientific knowledge authentic and reliable and what is the nature of explanation based on scientific knowledge. The topics which are explored in Philosophy of science by philosophers include scientific method, causation of different things, induction and distinguishing science from pseudo science which means distinguishing science from common sense.
Other questions are also addressed in the Philosophy of Science, such as realism of science, what is nature of existence of things which are still undiscovered, what is the limit of scientific knowledge and hence by answering these questions it adds an increment of knowledge on scientific theories and also to the critical thinking.
Philosophy of art is also knows as Aesthetics, finds out the answers of questions about nature and meanings of art and beauty. In this sense philosophers explore the questions such as how art is defined, what is the criteria to evaluate on artistic basis and what is relationship between art and emotions. Art has a role in society, artwork is interpreted, and influence of culture and history on art and artistic expression. It also includes creation and appreciation of art and explaining the influence of art on society.
