Let us now summarize the three general maxims we have discussed in this chapter. The three together state the conditions of a critical reading and the manner in which the reader should proceed to "talk back" to the author. The first requires the reader to complete the task of understanding before rushing in. The second adjures him not to be disputatious or contentious. The third asks him to view disagreement about matters of knowledge as being generally remediable. This rule goes further: It also commands him to give reasons for his disagreements so that issues are not merely stated but also defined. In that lies all hope for resolution.
