I would have thought that one can suspend one’s choice, and that this happens quite often, especially when other thoughts interrupt one’s deliberation. Thus, although it is necessary that the action about which one is deliberating must exist or not exist, it doesn’t follow at all that one necessarily has to decide on its existence or non-existence. For its non-existence could well come about in the absence of any decision. (Leibniz 1704 [1981]: 181)
