Children of the Lens by E.E. Smith

Each of the Second-Stage Lensmen had exactly the same facts, the same data, upon which to theorize and from which to draw conclusions. Each had shared his experiences, his findings, and his deductions and inductions with all of the others. They had discussed minutely, in wide-open four-ways, every phase of the Boskonian problem. Nevertheless the approach of each to that problem and the point of attack chosen by each was individual and characteristic.

Kimball Kinnison was by nature forthright; direct. As has been seen, he could use the approach circuitous if necessary, but he much preferred and upon every possible occasion employed the approach direct. He liked plain, unambiguous clues much better than obscure ones; the more obvious and factual the clue was, the better he liked it.
