My worldview was established around the time I was 13 or 14 and I doubt it will ever change.

That being said, the practical politics that it translates into have seen massive shifts in response to events. Harold Macmillan was once asked what the most troubling problem of his Prime Ministership was. 'Events, my dear boy, events,' was his reply.
