You do not have the moral option to choose not to learn. Choosing not to learn is choosing not to know what you will need to know in order to make a contribution to the world. Your chosen ignorance may be the occasion of an accident, the loss of life, the failure of an important project, the frustration of a community's dream, the disappointment of people who were counting on you to perform.
