I need ask nothing in return. The laws of exchange of matter being so very different from the laws of exchange of information, any attempt to trade ideas with material goods was destined for trouble sooner or later. Not only do people hold on to ideas for material gain,they also hang on to them for psychological gain. The ego likes to be identified as the source of a particular insight or concept. I did not make it happen.
Thoughts are free.
They should remain free, and be given freely. And, following the universal law, the more we give the more we shall receive. This is not a license to rip off. Let integrity prevail, and give credit where credit is due.
