ABSTRACT
The question of the criteria by which we test the validity of our convictions in analytical work is one of great practical importance in the day to day carrying on of our work, as we reflect upon the progress and the resistance to progress of our patients. It enters into the discussion of controversial issues between analysts, since everyone who puts forward new contributions may and should expect to be challenged as to the basis of his views and the tests and verifications to which he has subjected them. Lastly it is of central importance in the statement of our theory for the non-analytic public, who have the right to challenge our premises and conclusions and to be shewn our methods of testing and verification.
