One of the first philosophers, Socrates, was condemned to death and forced to drink hemlock because he asked too many questions. Many still think philosophers ask too many questions.
Philosophers ask questions because they want to understand what is really going on.
Scientists and moralists construct and defend scientific theories and moral principles, but philosophers want to know what moral principles and scientific theories are, and how they are developed and defended. Whatever the area, a philosopher is the one who asks the next question. God created the world, we are told, but the philosopher asks who created God, and then asks what the word 'created' or 'God' means in this conversation. As students progress in the study of philosophy, they begin to train their newly acquired critical abilities on questions that matter to them. A student majoring in philosophy and interested in literature or language, science or mysticism, morality, beauty, time, space, matter, mind, or the meaning of life, will be able to pursue that interest as far as he or she desires.
