One widely-encountered idea today is that there is no black and white when it comes to morality, only a kind of "gray area." This is often taken to mean that we really can't know with certainty what is right and wrong, allowing us to "push into the gray" as we make certain moral decisions that at first glance appear to be immoral.
The behavior of the semi-legendary figure of Robin Hood is sometimes mentioned as an example of this "gray area" phenomenon, since he was a character who would steal money (morally bad) for the purposes of helping the poor (morally good).
By focusing on the good intentions motivating our choices, and by arguing that morality is ambiguous and mostly "gray" anyway, a person can more easily justify and provide cover for morally problematic actions. When we begin to scrutinize the claim that morality is "gray," however, we encounter significant problems and contradictions.
The romanticized exploits of Robin Hood, for example, end up providing little more than a "veil of gray" that quickly dissolves when we place ourselves in the first-person situation of being the victim of his thievery, having our own windows broken and our own goods plundered. Those who have been robbed of their possessions will often describe afterwards, in vivid detail, the awful awareness of personal violation, the crushing of their feeling of security, etc. In these circumstances, we see the moral problem with Robin Hood's depraved actions, and appreciate the direct, black and white character of the universal moral injunction against stealing.
Universal moral prohibitions are clearly at the heart of any discussion about the "grayness" of morality. Many human actions, when freely chosen, will always be unacceptable. These actions, referred to as "intrinsic evils," are immoral regardless of circumstance. Adultery would be an example of an intrinsic evil. Regardless of how much a married man may desire to be with a new romantic flame, and regardless of how terrible his current marriage and sex life may appear to be, the decision to have sexual relations with someone who is not his spouse will invariably constitute an act of moral depravity on his part. Every wife who has suffered infidelity on the part of her husband, and every child who has seen the betrayal of their mother by their father can attest that there is no such thing as a "gray zone" for adultery. Many people who recognize that an action may be black may still be tempted to think that because their intentions are white, the "gray" action may be done. But good intentions cannot bleach the blackness of a deed.
Acknowledging the existence of intrinsic evils and recognizing the binding character of absolute moral prohibitions is an important part of our own moral growth and awakening. Indeed, morality itself, as an inner determinant of man's character, is not fundamentally "gray" at all, but is, by its very nature, a code of black and white. In the final analysis, the cult of moral grayness is too easily a revolt against fixed and essential moral values.
Although fixed moral values must always guide our decisions, correctly applying a general moral principle to a particular situation will often require specific knowledge of the circumstances and details of that situation.
