Second stage Lensmen by E. E. 'Doc' Smith

By coincidence, two science fiction books in a row.

The Lensmen of the title are men (yes, men) that are capable of mind-reading, projecting thought, and telepathy. They bring Civilisation to worlds run by authoritarians, I think. I lost track in the long introduction. There are also good superbeings, and bad superbeings.

Lots of very idealistic ideas of freedom and a absolute veneration of the authority of policemen.

A million beams, primaries raised to the hellish heights possible only to Medonian conductors and insulation, lashed out almost as once. Screens stiffened to the urge of every generable watt of defensive power. Bolt after bolt of quasi-solid lightning struck and struck and struck again. Q-type helices bored, gouged, and searingly bit. Rods and cones, planes and shears of incredible condensed pure force clawed, tore, and ground in mad abandon. Torpedo after torpedo, charged to the very skin with duodec, loosed its horribly detonant cargo against flinching wall-shields, in such numbers and with such violence as to fill all circumambient space with an atmosphere of almost planetary density.
