Through tackling with the actual problems that have been left beyond the scope of past philosophers, applied philosophy / ethics tries to reshape philosophical ideas as well as to solve those problem. In other words, it intends to renovate philosophy by taking seriously concrete problems in the real world rather than to apply one or another ready-made philosophical view to them in the manner of one-way traffic. Needless to say, for such an intellectual adventure it is essential to collaborate with other disciplines and people who are engaging real-world problems.
