How do we explain this contradiction?

This apparently intractable issue becomes fully resolved when the study of man is made in the light of the Divine Scheme of things. That is to say, when efforts are made to understand the will or plan of the Creator along with an understanding of the creation. This is the only possible scientific method that is of any relevance. When we approach matters from this angle, we realize that this problem confronts us only because we attempt to understand man without keeping in mind the creation plan of God. Man is a creation; he is not the Creator. Just as a machine is made by an engineer, it is not its own maker. This being so, if we want to know the reality of man, we have to learn about the creation plan of the Creator. Just as without the knowledge of the engineer's plan, we cannot explain the machine, similarly, without knowledge of the creation plan of the Creator, it is impossible to explain man. This is why, without keeping this creation plan in view, the meaning of man's life escapes us; whereas when we keep this creation plan firmly in view, everything becomes fully comprehensible. Everything falls into place.
