there's method in somebody's madness
there is (a) method in (one's) madness
There is a specific, rational purpose in what one is doing or planning, even though it may seem crazy or absurd to another person. I know you don't understand my motivation for this decision, but after the dust settles you'll see that there is a method in my madness. You may have method in your madness, but these radical changes to the business could still prove catastrophic.
