All things are lawful for me, but all things are not expedient: all things are lawful for me, but all things edify not.

-Bible (NewTestament)
Corinthians10:23.

The British Labour movement is today, and for many years has been, working in a narrow circle of strikes that are looked upon, not as an expedient, and not as a means of propaganda, but as an ultimate aim.

-Engels, Friedrich
  Letter to Eduard Bernstein,17  Jul.

'The true'to put it very briefly, is only the expedient in the way of our thinking, just as 'the right' is only the expedient in the way of our behaving.

-James,William
  Pragmatism, lecture 6.

It gave me a great notion of the credit of our present government and administration, to find people press as eagerly to pay moneyas they would to receive it; and, at the same time, a due respect for that body of men who have found out so pleasing an expedient for carrying on the common cause, that they have turned a tax into a diversion.

-Stein, Gertrude
