Any fact can be stated. Any act can be commanded. That is, they are tractable.
It is nonsense to speak of a fact but refuse to say what is thus to be seen. Likewise, it is nonsense to speak of an act but refuse to say who is to do it.
Of course, our statement may be misunderstood; our command may be disobeyed. But what has been misundertood, and who has disobeyed? It must be possible to say.
(It should perhaps be clarified that acts are never in past. Acts, once done, are now facts, to be seen. Likewise, there are no future facts, they are always behind us, in the past, where they may abide up to the present. "Who did that?" always refers to the fact that remains of some past deed.)
