excerpt "There probably is just a single intelligence or capacity to learn, not multiple ones devoted to independent tasks. To varying degrees, some individuals have this capacity, and others do not. To be sure, there is much debate about Gardner's theory in the literature, with contenders for and against. Nonetheless, empirical evidence has not been robust. While the theory sounds nice (perhaps because it sounds nice), it is more intuitive than empirical. In other words, the eight intelligences are based more on philosophy than on data.
