"Our object in these remarks has been not only to account for the slow progress which has as yet been made by Political Economy, and to suggest means by which its advancement may be accelerated, but also to warn the reader of the nature of the following Treatise"

Nassau William Senior is alerting the reader of the nature of the following Treatise in this quote. He is also attempting to explain why Political Economy has actually not advanced as quickly as it could have, and to suggest methods to speed up its advancement. Senior believes that the slow progress of Political Economy is due to a lack of understanding of the concepts of the topic, and a lack of appreciation of its significance. He suggests that the advancement of Political Economy can be accelerated by increasing the variety of individuals who are well-informed about the subject, and by encouraging more research and discussion of the concepts of Political Economy. He also encourages readers to be aware of the nature of the following Treatise, so that they can take advantage of the information it includes.
