Logic is an analysis of forms not a study of the mind.

Logic is an analysis of forms not a study of the mind. It tells 'why' an inference follows not 'how' it arises in the mind. It is the business therefore of the logician to break up complicated inferences from numerous premisses into the simplest possible parts and not to leave them as they are.
