Intensional Specifications of Truth-Conditions: 'Because', 'In Virtue of', and 'Made True ByaEuro¦aEuro™

Although a number of truth theorists have claimed that a deflationary theory of 'is true' needs nothing more than the uniform implication of instances of the theorem 'the proposition that p is true if and only if p', reflection shows that this is inadequate. If deflationists can't support the instances when replacing the biconditional with 'because', then their view is in peril. Deflationists sometimes acknowledge this by addressing, occasionally attempting to deflate, 'because' and 'in virtue of' formulas and their close relatives. I examine what I take to be the most promising deflationist moves in this direction and argue that they fail.
