Everyone carries a weight, some lighter, some heavier. The question raised is how best to bear it. Some say it depends solely on you, some say it depends solely on an Other. Whatever works is one approach. The best approach may be that carrying the weight depends on you and on an Other. Anyone trying to carry a long piece of lumber knows this.
Everyone who is not you carries a weight, some lighter, some heavier. The question raised is whether you have any responsibility to help, especially since you are already carrying your own weight. Some say you have no responsibility, some say you have absolute responsibility. Some say an Other will come along to help, some say that the Other is you.
