History shows us a lot of things. It shows why the Lord's Prayer includes the supplication: "And lead us not into temptation." In my day, dissertations were still written by hand, or drummed out with a typewriter. In the past, you had to round up the literature, find the books and find the passages. Nowadays you click on Wikipedia or Google and you have everything you need. This probably makes it more difficult to resist temptation.
