Reply #41: Oh, I know very well how they think.

[The Doctor.]

They think only in terms of the attainment and augmentation of power. That includes profit at any cost. It's not so much that they are 'irrational'. In fact, for the most part they are rational to a fault. What they are not is 'compromising' when it comes to those who are not of power. They truly believe that they should not have to deal with the burdens put upon them over the sheep.

They truly, truly believe themselves to be an entire class of higher species, if you'll excuse the mixed taxonomy. The reality is that they are, for the most part, entirely empty creatures with no real sense of their own value in the world at large.
