I glimpsed parts of a presentation recorded on A-PAC by Professor Sampford some time ago and it gave a definition to Dilema vs Temptation, to Lying, to Misleading, to Persuading.
Dilema = Principle 1 OR Principle 2
Temptation = Principle BUT the alternative leads to Personal Gain.
Lying = using a False Statement to induce a False Belief
Misleading = using a True Statement to induce a False Belief
Persuading = using True Statements to induce a Belief in what you Believe.
