This question can be assessed in terms of ''principles'' or ''reasons'' (reasoning and quotations), or ''evidence and documents. Principles are the same as prejudgements and principles regarding the topic; after agreeing on the above-mentioned issues, we assess the other topics; e.g. reasons, evidence, and documents.
