I'd say that, in the old, Victorian image of how the world works, there is definately strong evidence to suggest that there is a cosmic 'plan', and that all of our lives are following predetermined paths, dictated by the biological clockwork of our minds.
This viewpoint believes that the world is simple, logical, rational, traditional and predictable.
However, that viewpoint is no-longer widely believed in since the advent of relativity, quantum mechanics and notions of things like chaos theory, complexity theory and the study of emergent properties of complex systems.
