Plato’s Leaders

“Therefore we must elect as ruler and guardian of the city him who as boy and youth and man has been tested and has come out without strain, and render him honours in life and after death, giving him the highest rewards of public burial and other memorials. The others we must reject.” —Plato

What I find interesting is that in Plato’s opinion, we must actively reject the ‘others,’ and not, say, simply ignore them. I wonder if that’s got any deeper meaning?
