Logically speaking, the issue with Singer isn’t the
validity (validity and
truth are two different things) of his conclusions but the
truth of the premises his conclusions are derived from.
Apparently, as the article noted, Singer is regarded as being remarkably consistent in his beliefs and in the way he lives. Because of his consistency and his willingness to go where he thinks logic is leading him, his questions have great validity and we as Christians need to address them rather than simply dismissing them as the ravings of a deranged lunatic.
One essay of his that caused me to think a great deal about how I live my life is entitled “The Singer Solution to World Poverty.”
I wrote a short reflection based on this essay. If anyone is interested, they can read it
