The 'White' Choice

"If there is no black and white, there can be no gray-since gray is merely a mixture of the two." (Rand 87)

Rand goes on to say that since there must. be black and white to create gray one must first identify what is white and what is black on the scale of morality. Once they know what is black and what is white the person will not do whatever the black action is on the scale because that is the bad or wrong decision and the only decision they will make is the white decision; "There can be no justification for choosing any part of that which one knows to be evil." In reality however, how often does society reflect deeply on their moral decisions and the consequences of the actions have and even then, how often does society make the 'white choice' after considering those consequences? And on top of all of this, can we classify things into categories as rigid as black and white in the first place or is everything gray? I thought this was an interesting concept.
