The native, "victory of reason over animal instincts," is a state where instincts are subordinated to the requirements of reason and never take over the top mind when making strategic decisions, rather than when they are completely turned off. An analogy is the rider who then completely controls his horse when the horse fulfils all his demands unquestionably, rather than when the horse is rolled dead.
