Query: More than informative but less than satisfactory.

The main nominal context of this book is preluded by necessary but informative meaning.It failed however in its approach to pradocate the very imposition it was trying to assert.I dont think has the unifying thought failsafes that were all to abundant in previous attempts (Copi,Informal Logic) but it does appeal to the novice which is what makes it so accessible.
