We have all been present at discussions (or arguments) in which one of the combatants attempts to clarify or strengthen a point by comparing the subject at hand with another item or situation more familiar to the audience or opponent. More often than not, this stratagem instantly results in the protest that "you're comparing apples and oranges!" This is generally perceived as being a telling blow to the analogy, since it is generally understood that apples and oranges cannot be compared. However, after being the recipient of just such an accusation, it occurred to me that there are several problems with dismissing analogies with the comparing apples and oranges defense.

First, the statement that something is like comparing apples and oranges is a kind of analogy itself. That is, denigrating an analogy by accusing it of comparing apples and oranges is, in and of itself, comparing apples and oranges. More importantly, it is not difficult to demonstrate that apples and oranges can, in fact, be compared (see figure 1).

Materials and Methods

Both samples were prepared by gently desiccating them in a convection oven at low temperature over the course of several days. The dried samples were then mixed with potassium bromide and ground in a small ball-bearing mill for two minutes. One hundred milligrams of each of the resulting powders were then pressed into a circular pellet having a diameter of 1 cm and a thickness of approximately 1 mm. Spectra were taken at a resolution of 1 cm-1 using a Nicolet 740 FTIR spectrometer. Figure 2 shows a comparison of the 4000-400 cm-1 (2.5-25 mm) infrared transmission spectra of a Granny Smith apple and a Sunkist Navel orange.

Conclusions

Not only was this comparison easy to make, but it is apparent from the figure that apples and oranges are very similar. Thus, it would appear that the comparing apples and oranges defense should no longer be considered valid. This is a somewhat startling revelation. It can be anticipated to have a dramatic effect on the strategies used in arguments and discussions in the future.

Not to mention how they are formed from the reproductive structures of their respective parent plants and their purpose in the life cycle of plants. Both contain or are designed to contain seeds. Both have an amount of fruit sugar in them. Both are propagated in orchards by grafting. I guess oranges have an advantage as they are also the name of a color.
