The selection of an accidental word.

The selection of an accidental word.

Struggling with the choice of the alternative subject for my five thousand words essay, something occurred my mind. What about picking up an accidental word, any kind of word, which somehow would be chosen randomly and writing an essay about it?
If the selection happened in my mind only, I doubt it would be truly accidental selection. Even when attempting to do that, mind throws a million thoughts, which in their own way seem to be logic not accidental. It is funny how focused the mind constantly is. At the very moment, when the idea of random thought appeared it became impossible to actually process it in the mind only. Was it possible than before the idea appeared? It’s the same as asking if any thoughts and ideas are random and the answer is no. Therefore the random selection in the mind only can not ever happen.
The selection can be made by introducing the system, which somehow would be connected to the physical action. The number of possible systems is endless. How to pick on the right system than? Isn’t even the way of choosing the system somehow influenced by the actual content of the mind, therefore by the knowledge and experience? The answer is no, because it depends on how precise the system is.
The perfect system must include the list of all existing words. However another problem appears. The system would be probably more precise if the list of all existing words would be made in all existing languages.
