The law of contradiction is a logical law and does not apply to the many variables of electricity. Poor analogy.
Relative and absolute are not things. To say something is both relative and absolute does not violate the law of contradiction because the law only applies to things "in the same context." So, moral principles are determined by the nature of the case (just like Ohm's law) but how those principles are applied are determined relative to the facts of each case. Any other law is arbitrary, having no relationship to reality or real values.
Baloney. n You do not understand basic logic. The law of contradiction recognizes that human reality is based on "antithesis," and deals with "either/or" questions. Not all questions are either/or questions but whether something is aboslute or relative is indeed an either/or question. A leaf is either green or it is red. Which is it? I either exist or I don't. Which? You heart is either beating or it isn't. Which? Moral absolutes are either from God (absolute) or from man (relative). Which? Can't be from both at the same time. Besides, no moral from a man can possibly be absolute becuase moral absolutes are universal in scope and nothing man can do is universal. You need more thinking in this.
...10 commandments - these are REAL moral absolutes... But you do not believe they are really absolute. Why should anyone else. Oh, I absolutely do - because they are! Is lying wrong or not? Is stealing wrong or not? Is murder wrong or not? Is adultery wrong or not (ask Ayn Rand that one!).
The Sabbath is the 7th day of the week. Do you remember Saturday to keep it holy? Or, do you worship on Sunday.
Now, the ten commandments are either absolute or they are not.
