I think if you dig in to many modern medical treatments, you'll find that the true reason they work is unknown (and in many cases, there is little evidence that they work at all).

Even in the hard science of physics, we we can understand the cause and effect, but the fundamentals of nuclear forces, gravity, magnetism are all a complete mystery.

But there's certainly hope that someday we'll be able to explain through physics how come we hope to explain hope and understanding through physics.
