Presuppositions in Linguistics

 Inspired by the concept of Presuppositions in Linguistics, I would just like to float a concept which I call Proactive verbs and Reactive verbs.

Reactive verbs are those actions which require an already existing prevalent reality to which the doer is reacting. Proactive verbs are those actions which aren't reactions to any prevalent reality existing, before doing the action. Technically speaking, every verb will be reactive.

E.g. - 'harvesting' is a reactive verb, because the action of harvesting can take place only when crops have already grown and filled the field. This is the prevalent reality. But 'dancing' is a proactive verb because you can start dancing without the presence or requirement of anything particular in reality. You can just start dancing on the floor or in space. Now, strictly speaking, technically, every action will have some requirements, i.e. the proactive verbs like dancing will require a floor or space and obviously the doer (and some might say intent), or slipping will require a surface and the one who slips, but that is too basic and commonsensical. For all practical purposes, harvesting is reactive and slipping and dancing are proactive. 

This seems to be the basis of the sentences associated with presuppositions like 'John has stopped watching cricket', which implies that John once watched cricket. This is because 'stopped' is a reactive verb. You stop something when something is already going on / in action, before.
