Measure Twice. Cut Once?

Sometimes it can be helpful to think before acting. Even more, it can behoove one to keep thinking after acting. If you take a turn and it seems to lead to an unfamiliar place, getting the map back out can help. Trace where you were to wherever you are, and then where you wish to go. Maybe you'll keep trucking down that same road; maybe you'll take a sharp turn to find a better route. There is no GPS to life, for that we have minds and memory and feelings; in fact, that's why we get on the road in the first place.

The following is copied from the Wikipedia. The full article is even more informative. As it implies: no certainty; no GPS. But we do know where the road led back then.

The Reichstag fire, a pivotal event in the establishment of Nazi Germany, began at 9:14 PM on the night of February 27, 1933, when a Berlin fire station received an alarm that the Reichstag building, assembly location of the German Parliament, was ablaze. The fire seemed to have been started in several places, and by the time the police and firemen arrived a huge explosion had set the main Chamber of Deputies in flames. Looking for clues, the police quickly found Marinus van der Lubbe, naked, cowering behind the building. Van der Lubbe was a Dutch insurrectionary council communist and unemployed bricklayer who had recently arrived in Germany. Adolf Hitler and Hermann Göring arrived soon after, and, when they were shown van der Lubbe, Göring immediately declared the fire was set by the Communists and had the party leaders arrested. Hitler took advantage of the situation to declare a state of emergency and encouraged aging president Paul von Hindenburg to sign the Reichstag Fire Decree, suspending the basic rights provisions of the Weimar constitution.
