Why is philosophy sometimes considered as a child of failure?

It is obvious that human efforts alone have not succeeded in finding the truth about life, and it seems that they never will. There is good reason, then, to conclude that some kind of divine revelation is necessary. What many call the book of nature provides some revelation. Even if it does not give conclusive details about the origin of life, it does show that there is something far more satisfactory than a purely materialistic explanation of life. A blade of grass that grows upward actually follows laws other than those governing a pile of rocks in a crumbling hole. Living things in nature build and organize themselves in a way that dead things do not. A noted student of law and religion thus had a basis for concluding: “[God’s] invisible qualities are clearly seen from the world’s creation onward, because they are perceived by the things made.”—Romans 1:20.
