There is no justification without sanctification, no forgiveness without renewal of life, no real faith from which the fruits of new obedience do not grow.
Martin Luther
A structure becomes architectural, and not sculptural, when its elements no longer have their justification in nature.
Guillaume Apollinaire
An explanation of cause is not a justification by reason.
C. S. Lewis
The modern conservative is engaged in one of man's oldest exercises in moral philosophy; that is, the search for a superior moral justification for selfishness.
John Kenneth Galbraith
Any work that aspires, however humbly, to the condition of art should carry its justification in every line.
Joseph Conrad
