Philosophy is often called the mother of all sciences. Disciplines like physics and psychology originated from philosophy. For a long time, philosophers were the only scientists trying to understand reality, whether physical or social. 
But philosophy is more than that, because it explores important issues that go beyond scientific research, actively engaging with the most important issues of our lives.

What does it all mean? Can we decipher what is good and evil? Does it make sense to distinguish mind and body? What does a social and international order look like in which basic freedoms can be fully realised? Is art important for our happiness?

These questions correspond to five interrelated subdisciplines of philosophy: 
philosophy of language, ethics, philosophy of the mind, political philosophy and philosophy of art.
