duties and responsibilities?are they different or the same?

I think basically the two words mean the same thing, but I'd personally say they differ in that duty is assigned to you (say your job, for example), whereas responsibility is not really being forced on you by a higher authority, it's just the things you know or SHOULD know you should be doing.

I remember a similar issue came up once in a lecture by Robert LeFevre. He tried to make the distinction between the words "responsibility" and "obligation". He pointed out that although the two had come to mean almost the same thing, they didn't always. The difference, he claimed, is in the tense.

Responsibility, he claimed, was a past tense word. To be responsible for something is to have caused a given effect. It's sort of like saying, "you had/were assigned the power over X, therefore, whatever happened with X is due to you"

Obligation, he claimed, is future tense. It is something that we choose. If you have an obligation to X then in the future you will be "responsible" for X.

I think duty is something you do for or something that is due others. For example, it's the duty of the parents to take care of their children. Or you have a duty to work on the job assigned to you by your boss. It's your duty to sweep the floor, throw the garbage, etc. Whereas responsibility is something you hold yourself accountable for.

they are diferent...duties are things that we are suppose to do ...like children has their duties to study...but responsibility covers all the people around us...e.g:it's the responsibility of my class leader to submit all of our notes...these words seem to have the same meaning but they are different
