The following is a brief quote from an article about Gardner's Multiple Intelligences:

"Bruner identified three major classes of knowing: iconic, enactive, and symbolic (Bruner, et al., 1967). Iconic was linked to the ways of knowing central to the visual and spatial arts; enactive knowing framed the wisdom of movement, kinesthetic action, and dance; and symbolic represented the realm of reason and reductive logic (Samples, 1992). Schools have depended primarily on the symbolic and have measured intelligence in terms of achievement in this realm."
