In Monty Python and the Holy Grail, logic is used in an unfamiliar way. This logic does not deal with the nature of life, but deals with the more complex forms of logic that require the filling of blanks to make things work out. Although, for the most part certain things did not make sense, but yet they did express logic. They used environmental attributes to make sense of the complexities they had.
The first application of logic found in the movie was in the first scene with the use of coconuts. They argued about how King Arthur had coconuts here in a moderate climate while coconuts only grow in tropical climates. King Arthur's explanation for this was that a swallow brought it back when migrating. The peasant said that is impossible because a little bird cannot carry a coconut while it migrates. Hence with no other possibilities the peasant had concluded that it is impossible to have a coconut in England, which had been brought back, from a tropical area from a small migrating bird. This is a perfect example of how the movie breaks down logic and uses the settings environmental attributes and resources. Another example of this uncouth logic is seen with the town's people's belief of the woman being a witch. The town's people said that she shall be burned for being a witch, but the knight, in his use of logic says that if she is a witch, and must be burned then she is made of wood. The knight goes on to say that if she is made of wood then she must float, and that if she floats she must be the same weight as a duck. So they weigh her and from the magic of movies she weighs the same as the duck, concluding that she is a witch. This shows the irrational logic that is being used in the movie, as well as the use of environment to draw a basis for conclusion. From this they arrive at the same conclusion they had in the beginning, that being that the women was a witch. Overall, the use of logic in Monty Python and the
