Personally I don’t believe there are any limits to my responsibilities other than pragmatically; that is, what I can realistically accomplish. Fundamentally, I owe everything I have, am and will ever be to my society, and likewise am deeply indebted to every personal relationship in my life for nourishing and nurturing me and inspiring me to grow. What mitigates my responsibilities - that is, the quality and extent of my “response” to these incredible gifts - is my time, energy, accessible resources, life-balance, integrity in adhering to my own values hierarchy, and the priorities, agreements and contracts I have already committed to. In other words: where one area of indebtedness competes with another area of indebtedness, I am forced to prioritize and of necessity exclude some actions. There is only so much time in a day. However, if I had unlimited time, unlimited resources, and unlimited personal energy, then my responses from a place of affectionate compassion (on a good day) or dutiful obligation (on a baseline day) would be equally limitless.
My 2 cents.
