The role of galaxy motions in the heating of intracluster gas is discussed. It is shown that if galaxies in the cores of clusters have mass-to-light ratios greater than about 30, than heating by gravitational drag can replace the heat lost by radiation, even in clusters where the cooling time is short compared with the Hubble time. It follows that cooling flows may not be as prevalent as has recently been supposed, and the predicted formation of up to 10 to 13th solar mass of stars from the gas in rich clusters may not occur. Reversing the argument shows that most of the virial mass in clusters cannot be bound to individual galaxies. The optically emitting filaments observed in clusters of galaxies may be due to thermal instability of the intracluster gas, but a high rate of mass accretion is not required to explain their luminosities if they are photoionized by surrounding warm gas.
