Wittgenstein's "problem on the irreducibility of rules" is brainfart at best. Any rule that can be actually _followed_ cannot be logically precise, and vice-versa. If you try to reduce anything from the real-world to pure logic you'll surely end up crazy.

there are abstract rules and practical laws, principles, whatchamacallit. Laws bind abstract rules to real thingies. The ground truth values are right and wrong en lieu of good and bad - basic emotions that are at the basis of experience. Trying to verbalize (the word logic is related to logos, old greek for tongue, language logic) every basic emotion you will surely go irrationaly crazy. Therefore, context is assumed and language is underspecific.
