I loved the opportunity to think about the big questions philosophy asks, and the rigorous way in which philosophy trains the mind to answer them. What is ultimately real? Why is there something rather than nothing? Is there a necessary being or are all beings contingent? What is knowledge and what can we know? Is there something which is objectively right or wrong, or is everything relative? Most people, at some point, will be confronted with some of these questions and will try to answer them in a more or less informal way. Philosophy has been tackling them over the centuries in a formal, rigorous way, engaging in a deep, fascinating, and exciting conversation which continues nowadays.
