There's an evolutionary imperative why we give a crap about our family and friends, and there's an evolutionary imperative why we don't give a crap about anybody else. If we loved all people indiscriminately, we couldn't function.
David FosterThe really important kind of freedom involves attention and awareness and discipline, and being able truly to care about other people and to sacrifice for them over and over in myriad petty, unsexy ways every day. That is real freedom. That is being educated, and understanding how to think. The alternative is unconsciousness, the default setting, the rat race, the constant gnawing sense of having had, and lost, some infinite thing.
