Professor Higgins is seen throughout Pygmalion as a very rude man. While one may expect a well educated man, such as Higgins, to be a gentleman, he is far from it. Higgins believes that how you treated someone is not important, as long as you treat everyone equally.

Higgins presents this theory to Eliza, in hope of justifying his treatment of her. This theory would be fine IF Higgins himself lived by it. Henry Higgins, however, lives by a variety of variations of this philosophy. It is easily seen how Higgins follows this theory. He is consistently rude towards Eliza, Mrs. Pearce, and his mother.

When in "the state" Henry Higgins wanders aimlessly around the parlor, irrationally moving from chair to chair, highly unlike the calm Professor Higgins we see at the ball. Higgins does not believe that a person should have the same...
