Consider Immanuel Kant's discussion of a categorical imperative and make at least one mention of it.
Yep, every article I have seen about this kind of issue involves a reference to Kant. You can also talk about the difference between Kant's deontological ethics and Mill's utilitarianism. It is a great subject to study! But for now let's work on the essay.
Yet, how is about a patient who practices the speaking of untruths to himself?
Now looking back, he admits that if he had not lied himself he would not have been a legend nowadays.--- wow, very impressive!! You have a good point.
Sometimes it is necessary to lie to others to compensate for their unreasonableness, ha ha... like when they have a knife and are waving it around, you can say, hey, the cops are on the way! Even if they are not...
Hey, actually it really would be good to look into absolutism vs. utilitarianism. Here is a link:
I think you will enjoy that. This is about utilitarian ethics:
"If the end does not justify the means-what can?-Edward Abbey"
The way to improve the essay is to revise to speak in terms of the discussion of whether Kant is correct that lying should be categorically forbidden or whether Mill is correct that the end justifies the means.
