I mean worth to refer to those things we prize and yet say you can’t put a price on it. We derive value, on the other hand, from the comparison of one thing with another. I cannot express the value of linen in terms of linen, says Marx in the classic analysis of commodities which opens his Capital. Value needs a difference for its expression; when there is no difference we are left with tautology (a yard of linen is a yard of linen)."; // original the text
