Now imagine that the two heterogeneous representations \(a\) and \(\alpha\) are joined by representations belonging, respectively, to the same types as those already present, e.g., color-representations, \(b\) and \(c\), and sound representations, \(\beta\) and \(\gamma\) (SW V: 308). Here \(b\) and \(c\)’s appearance in the same color continuum as \(a\) results in the mutual inhibition of \(a\), \(b\), and \(c\), so that \(b\) and \(c\) amount to what Herbart calls an “incidental obstacles” to the complete complication of \(a\) and \(\alpha\) (SW V: 309).[36] (The same of course holds for \(\alpha\), \(\beta\), and \(\gamma\).) Hence \(a\) and \(\alpha\) can at best join in an “incomplete complication” (SW V: 309). Clearly these make up the vast majority of our compound representations (Felsch 1902: 5).
