"Once is orthodox, twice is puritanical"

Too much of anything can be harmful, and it is important to find a middle ground. The phrase "as soon as is orthodox" indicates that doing something when is the correct amount, while "twice is puritanical" suggests that doing something two times is excessive. This quote is a suggestion to not take things too far and to find a balance in between extremes. It is a pointer to practice small amounts and to not be too severe in any situation. Lord Melbourne's quote is an amusing way of advising us to discover a balance in between extremes and to practice small amounts in all aspects of life.
