James Boswell Quote
'Sir,' said Mr Johnson, 'a lawyer has no business with the justice or injustice of the cause which he undertakes, unless his client asks his opinion, and then he is bound to give it honestly. The justice or injustice of the cause is to be decided by the judge.'
(15 August 1773) - The Journal of a Tour to the Hebrides with Samuel Johnson, LL.D. (1785)
