In the third of the examples, "The space is bounded by three straight lines, _therefore_ it is triangular;" the order of the predications is inverted, the _conditioning_ being put first. In this case, therefore, we need a mark to show that the last predication is conditioned, and conditioned by the preceding. This is done by prefixing to it the compound word, _therefore_, of which the first part _there_ is equivalent to _that_, and _fore_ or _for_ means _cause_. The expression in its elementary form being, "The space is bounded by three straight lines; for that, or cause that, the space is triangular." In these cases we have examples of what are called, the Suppositive, the Causal, and the Illative conjunctions. The following are examples of what are called the Disjunctive. "The ship was well manned; _else_ it would have been lost." "_Unless_ the ship had been well manned, it would have been lost." In these two examples, the conditioning *predications are, "The ship was well manned;" "The ship had been well manned:" the _conditioned_ is, "it would have been lost," in both instances. The dependence here, between the _conditioning_ and _conditioned_, is that of physical consequence. The ship's not being lost, was the consequence of its being well manned. The contrivance for marking this dependence is akin to that which we have traced in the former instance. In the first of the two examples, the _conditioning_ {218} predication stands first. How do I mark that the next is _conditioned_, and conditioned as a physical consequent? I interpose the word _else_. This is part of an obsolete verb, signifying, _to dismiss_, _to turn out_, _to take away_.[66] And the sentence is thus resolved: "The ship was well manned," _take away that_ (take away the cause, the effect is taken away also) "she would have been lost." [Findlater's footnote 66: _Else_ is the genitive of an obsolete adjective, in Gothic _alis_, corresponding to Lat. _alius_; and is analogous with Lat. _alias_.--_F._] Other conjunctions of the disjunctive kind, as they are called, would here have answered the same purpose with _else_. "The ship was well manned, _otherwise_, she would have been lost." _Otherwise_ here is precisely of the same import as _else_. "The ship was well manned;" that being dismissed, that being _other_ than it was; "it would have been lost." "The ship was well manned, _or_ it would have been lost." _Or_, in German _oder_, is _other_. The resolution of this sentence, therefore, is the same as the former.
