Poems inspire our trust, argues James Longenbach in this bracing work, because they don't necessarily ask to be trusted. Theirs is the language of self-questioning—metaphors that turn against themselves, syntax that moves one way because it threatens to move another. Poems resist themselves more strenuously than they are resisted by the cultures receiving them.

But the resistance to poetry is quite specifically the wonder of poetry. Considering a wide array of poets, from Virgil and Milton to Dickinson and Glück, Longenbach suggests that poems convey knowledge only inasmuch as they refuse to be vehicles for the efficient transmission of knowledge. In fact, this self-resistance is the source of the reader's pleasure: we read poetry not to escape difficulty but to embrace it.

An astute writer and critic of poems, Longenbach makes his case through a sustained engagement with the language of poetry.
