"Discarded in favor of self destruction"

Rational thought clearly counseled the Trojans to suspect a trick when they woke to find the entire Greek army had vanished, leaving only a strange and monstrous prodigy beneath their walls. Rational procedure would have been, at the least, to test the Horse for concealed enemies as they were urgently advised to do by Capys the Elder, Laocoon and Cassandra. That alternative was present and available yet discarded in favor of self destruction.
— From Barbara Tuchman’s The March of Folly, about why governments do things that are clearly contrary to their own self-interest. p 380
