Why assume that the laws will be consistent?
Why assume that we will be able to discover them?
Tell us where the laws of physics have been abridged. Forensics, the Principle of Uniformity, scientific method all seem to depend upon these principles which allow us to apply the philosophical law of logic.
As to why we will be able to discover them, I suppose one might assume that we might never discover anything. But, science is the process of discovery and of discovering causes. Scientist have been laborously working for centuries to discover an order imposed upon this universe. I suppose we could all stop that now.
