Can't have gone means incredulity, improbability (It's hardly possible that, I refuse to believe that, etc.). It doesn't matter if you use can't or couldn't in this meaning. Perfect Infinitive is used to denote past, of course. And the context proves it. It shows what place the person reached/arrived at/got. - this is what I think about it :) _________________ I am an incurable optimist. |

Hi,
It doesn't matter whether it is in present or past - who actually cares? What is important is whether you understand it or not. Think about it. :)

From Then (when he left) to Now (when we are speaking), he can't have gone far.
The present perfect is a present aspect/tense. Above, we ask "where IS he at THIS moment". There, the present perfect is being used in its resultative sense. |

But as far as I know ,when perfect infinitive goes with modals, it indicates a past action.But is it true that it depends on the context to understand ? _________________ Don't see your shade think you are great |

The action he has gone is in the past. (or he hasn't gone far, or he can't have gone far). If it were in present you'd have He can't go far = he is not able, though it sounds awkward. _________________ I am an incurable optimist. |

. I might interpret 'He can't have gone far' this way: 'It just isn't possible that he has gone far'. . _________________ "Nearly all men can stand adversity, but if you want to test a man's character, give him power." ~ Abraham Lincoln |

Not sure who is arguing that the going was not in the past. Who is? |

Or "it is not possible that he IS far (away)". |

Present perfect: Used to relate events or states taking place in the past to a present time orientation.
--------
The present perfect represents a secondary past in the present, and thus references both a primary present and a secondary past relative to it. The narrative time is present [the sentence is about the present], but the event time of the sentence is past.

Maybe duc needs to go back to the basics of using the present perfect and modals. |
