Sorry, but my fragile, egg-shell mind has no idea what you're talking about.

Ghosts crowd the young child's fragile eggshell mind
Human beings have been making practical use of the "principles of evolution" in animal and plant breeding for thousands of years. They didn't need any "theory of evolution" to do so.
A bit of an odd semantic victory that you are claiming here. Consider what the differences are between the principles of a process and the theory of a process. Take flight for example. The principles have always been there and exist independently of any explanation of them. We can shoot an arrow or throw a rock without having the slightest notion about why they follow the trajectory that they do. However, with the development of a theory of flight that explains and defines the principles involved we are able to predict what might happen if you strap an engine to a pair of wings.
So using only the principles of biology we could continue probing around in the dark to see what works and what doesn't. Essentially just try everything until something works for you. Similar to the way that a child approaches the world. Now then if you accumulate the observations and filter them through a non eggshell like mind you have a chance of producing a theory that can bring some direction to your studies.
An even better analogy might be that principles are like the roads and a theory is like the map. Can you think of any practical use for a map?
