An empirical method for decomposing the infrared continuum of AGNs into thermal and nonthermal components is introduced. Based on the results, it is postulated that all Seyfert 1 nuclei could have the same underlying continuum energy distribution modified by dust absorption and thermal reemission. Additional evidence is examined, and it is found that this interpretation of the infrared continuum is supported by a variety of data. Finally, the spatial and temperature distribution of the infrared-emitting dust component of the nucleus and its relation to central source luminosity are addressed. 56 references.
