We understand what we ought to do; but when we deliberate we play booty against ourselves: our consciences direct us one way, our corruptions hurry us another.
Only imagine a man acting for one single day on the supposition that all his neighbours believe all that they profess and act up to all that they believe. Imagine a man acting on the supposition that he may safely offer the deadliest injuries and insults to everybody who says that revenge is sinful; or that he may safely intrust all his property without security to any person who says that it is wrong to steal. Such a character would be too absurd for the wildest farce.
Lord Thomas Babington Macaulay: Sir James Mackintosh, July, 1835.
