The secular evolution of galactic discs, of which the increase of the stellar velocity dispersion with age is the most striking expression from a kinematical point of view, is closely related to their stability properties because of the collective nature of such systems. In this context, however, the crucial role of collective effects is often underestimated or not properly taken into account.
