If you prefer substitute 'principles, concepts, methods, and metacognitive skills' for 'tools'. Try not to get hung up on the precise labels. Factual knowledge is only a small part of what we are talking about here. The 'critics' have an entirely different toolset from 'practitioners'. Even their factual knowledge is of a different type, grounded in a different context, and not easily comparable. Likewise it doesn't make much sense to compare their 'accomplishments': criticism is its own valuable discipline with different goals.
