In this video John Hittinger briefly describes why philosophy is so important to study. He also points out the fact that it is important to understand the differences between modern philosophy and that of the ancients. More importantly we need to recognize the modern philosophies and how they are applied in today's culture. The thoughts of the modernist philosophers have deeply penetrated the thought of world in which we live, and it is crucial to know what the philosophical remedy is to their error. Unfortunately many in the Church today fail to grasp the importance of this issue, and this is why I believe that Catholic apologetics is in such a state of decline today. We can find the remedy in the video below by Fr. Robert Barron.
