"Doing philosophy - thinking and arguing about it, not just passively reading it - develops our critical reasoning abilities, and so equips us for many challenges of the rapidly changing world... More surprising, and possibly even more significant than the benefits of doing philosophy for general reasoning abilities, is the way in which taking a philosophy class can change a person's life."
