Kant said that when judging the morality of an act, we must weigh the intentions of the actor. Was he acting selfishly, to benefit himself, or selflessly, to help others? By this criterion, Gleick’s lie was clearly moral, because he was defending a cause that he passionately views as righteous.He fudges a bit in the third sentence, switching from selfish vs. unselfish to "passionately views as righteous." What he should have said is that Gleick's lie was clearly moral because he was acting to help others. Whether the 'others' are people or trees or bugs is immaterial. As I've discussed elsewhere, there is no standard to judge helping others and this principle therefore is carte blanche to lie, steal and cheat as long as you can claim to be acting selflessly.
Contrast Kant's and altruism's moral blank check for dishonesty with Ayn Rand's description:
Honesty is the recognition of the fact that the unreal is unreal and can have no value, that neither love nor fame nor cash is a value if obtained by fraud—that an attempt to gain a value by deceiving the mind of others is an act of raising your victims to a position higher than reality, where you become a pawn of their blindness, a slave of their non-thinking and their evasions, while their intelligence, their rationality, their perceptiveness become the enemies you have to dread and flee—In fact Gleick was counting on not just the blindness of the Heartland Institute, but of the entire internet community. That didn't work out so well. The bloggers' intelligence, rationality and perceptiveness outed him pretty quickly and he's been removed from the ethics committee he chaired (!) and taken a leave of absence from his job. If only the Kantian professors whose creed justifies Gleick's actions were put on leave as well.
[Honesty is the recognition of the fact]—that you do not care to live as a dependent, least of all a dependent on the stupidity of others, or as a fool whose source of values is the fools he succeeds in fooling—that honesty is not a social duty, not a sacrifice for the sake of others, but the most profoundly selfish virtue man can practice: his refusal to sacrifice the reality of his own existence to the deluded consciousness of others.
