Charity is having patience with someone who has let us down. It is resisting the impulse to become offended easily. It is accepting weaknesses and shortcomings. It is accepting people as they truly are. It is looking beyond physical appearances to attributes that will not dim through time. It is resisting the impulse to categorize others.
It will not be we who reach Alpha Centauri, and the other nearby stars. It will be a species very like us - but with more of our strengths and fewer of our weaknesses.
I think that everyone has something about themselves that they feel is their weakness... their 'disability.' And I'm certain we all have one, because I think of a disability as being anything which undermines our belief and confidence in our own abilities.
