2. The _perfect indicative_ represents something as now completed--as begun in the past but continuing till the present, at least in its consequences: as, "I _have lost_ my book" (so that now I do not have it); "This house _has stood_ for ninety years" (it is still standing); "Bishop Brooks _has died,_ but he _has left_ us his example" (he is not now among us, but we have his example).
3. The tense of the verb in a dependent clause varies with the tense of the princ.i.p.al verb:[81] as, I _know_ he _will_ come.
I _knew_ he _would_ come.
I _have taken_ the first train, that I _may_ arrive early.
I _had taken_ the first train, that I _might_ arrive early.
Blanche _will be_ frightened if she _sees_ the bat.
Blanche _would be_ frightened if she _saw_ the bat.
Blanche _would have been_ frightened if she _had seen_ the bat.
Present facts and unchangeable truths, however, should be expressed in the present tense, regardless of the tense of the princ.i.p.al verb: as, "What did you say his name _is_?"
4. The _perfect infinitive_ is properly used to denote action which is completed at the time denoted by the princ.i.p.al verb: as, "I am glad _to have seen_ Niagara Falls;" "He felt sorry _to have hurt_ your feelings."
EXCEPTION.--_Ought, must, need,_ and _should_ (in the sense of "ought") have no distinctive form to denote past time; with these verbs present time is denoted by putting the complementary infinitive in the present tense, past time is denoted by putting the complementary infinitive in the perfect tense: as, "You ought _to go_," "You ought _to have gone_;" "He should _be_ careful," "He should _have been_ careful." A similar change from the present to the perfect infinitive is found after _could_ and _might_ in some of their uses: as, "I could _go_," "I could _have gone_;"
"You might _have answered_."

[81] This is sometimes called the "Law of the Sequence of Tenses."
