With the qualification stated in the following sections a plaintiff can recover for breach of contract compensation for only such consequences of the breach as are both proximate and natural. When a seller wrongfully fails to deliver the promised goods, the buyer's damage from inability to use them for a special profitable purpose he has had in mind is a consequence which is proximate, but not natural or to be reasonably expected by the seller. The law of torts and of contracts differ in this respect. For a tort the defendant becomes liable for all proximate consequences, while for breach of contract he is liable only for consequences which were reasonably foreseeable at the time when it was entered into, as probable if the contract were broken.26 For these he is liable whether they were actually foreseen or not,27 or whether even the criminal act of a third person intervenes.28
