There is no part of the administration of government that requires extensive information and a thorough knowledge of the principles of political economy, so much as the business of taxation. The man who understands those principles best will be least likely to resort to oppressive expedients, or sacrifice any particular class of citizens to the procurement of revenue. It might be demonstrated that the most productive system of finance will always be the least burdensome.
Alexander Hamilton

Jane Austen

John Locke

An accomplished woman is one who has a thorough knowledge of music, singing, drawing, dancing and the modern languages; she must be well trained in the fighting styles of the Kyoto masters and the modern tactics and weaponry of Europe.
