We all know what it means to 'make a virtue out of a necessity'. The only bananas on offer at the supermarket are 'fair trade', so we buy them and then pretend to ourselves and others that we have done something virtuous. Or a company is obliged by its employment contracts to pay double the statutory severance terms, but it parades the fact of having done so as generosity on its part.
But I am thinking of a slightly different situation. Let us consider the case of low-energy light bulbs. It is my contention that they do not give off as much light as the old equivalent high-energy ones. But we are using them as a contribution to saving the planet from global warming. But what I find particularly annoying is people who will insist that the bulbs give the same light value.
One sees this attitude all the time. Because something has virtue, yet incorporates drawbacks, some people will insist that the drawbacks do not exist.
Does this amount to the corollary i.e. does it 'make a necessity out of a virtue'? Or how else do we describe such thinking?
