*Support Structures* is a manual for what bears, sustains, props, and holds up. It is a manual for those things that encourage, give comfort, approval, and solace; that care for and provide consolation and the necessities of life. It is a manual for that which assists corroborates, advocates, articulates, substantiates, champions, and endorses; for what stands behind, underpins, frames, presents, maintains, and strengthens. Support Structures is a manual for those things that give, in short, support. While the work of supporting might traditionally appear as subsequent, unessential, and lacking value in itself, this manual is an attempt to restore attention to one of the neglected, yet crucial modes through which we apprehend and shape the world.
