To educate the intelligence is to expand the horizon of its wants and desires.
In a higher phase of communist society… only then can the narrow horizon of bourgeois right be fully left behind and society inscribe on its banners: from each according to his ability, to each according to his needs.
The health of the eye seems to demand a horizon. We are never tired, so long as we can see far enough.
In 50 years – or 20 years, or 200 years – our current epistemic horizon (the Big Bang, roughly) may look as parochial as the horizon Newton had to settle for in his day, but no doubt there will still be good questions whose answers elude us.
