Our signature confirms that the content of an act is our own work and not the work of another. Our attempt to deny our work is powerless when the work carries our own handwritten signature and not the handwritten signature of someone else. And it is well known in history that many have tried to intercept the content of an act by altering and violating the signatures.
However, in modern times theft is relatively easy to uncover, because we always leave personal traces, and if anyone wants to counterfeit or appropriate our own work, reality contradicts them. The social environment can have an effect on some of our actions, but the act itself always bears our signature and the contribution of social influences cannot be an alibi for an act we would like to forget.
Taking on the responsibility of an act with our mark is the safe prerequisite for any serious effort if we want to forget the bad past and build a safer, healthier and more efficient personal future.
