We have discovered that the POLARIZED FLUX (scattered light) spectra of NGC1068 and other Seyfert 2 nuclei look like the FLUX spectra of Seyfert 1 nuclei. This implies that these objects would appear as Seyfert 1's if viewed from another direction, so the distinction between the two classes could be a largely an orientation effect. (The polarization position angles of Seyfert 2's are always perpendicular to the radio source axes. This scattering geometry indicates that the Seyfert 2's would appear as Seyfert 1's if viewed along the radio jet axis.) We need to find out whether or not the polarized flux spectra of Seyfert 2's are really INDISTINGUISHABLE from the flux spectra of Seyfert 1's by looking for the high excitation lines, the Fe II, and the continuum shape in the UV. We also need to measure the wavelength-dependence of continuum polarization in the UV to determine the nature of the scatterers.
