Paul knew that Torah with all its rituals and sacrifices did not originate with God (Jeremiah 7:22; 8:8), hence he warned Christians to guard against ‘deceptive’ philosophy that would take them back to Torah. (Colossians 2:8 Compare 2:11, 16, 17) In view of the over-all view of the Bible, there is no excuse to use the word philosophy with any negative connotation. JWs built their stand on philosophy based on this wrong (negative) use of the word philosophy found in Colossians 2:8.
The Greek word phi·lo·so·phi´a means “love of wisdom.” And wisdom means “fear of God.” (Psalm 111:10) Fear of God means hatred of doing wasteful things (Proverbs 8:13) and is contrasted with “licentiousness” (Proverb 10:23, 27). Thus philosophy ultimately means ‘taking delight in doing God’ will, or doing good to others without expecting anything in return.’ (Psalm 112:1; Mathew 5:44-48) This is nothing but sheer common sense! Everyone knows he is an individual (means indivisible) as he came FROM GOD, through his parents.In between there is no separation, as neither anyone authored his birth nor his parents authored their children’s birth. Hence all are individuals, indivisible (indivisible part of WHOLE); hence have no reason to hate another or put one’s interest above the other. This is what Socrates meant when he said “know yourself” which he called “the highest knowledge.” This is the essence of philosophy which is synonym with “taking delight in the welfare of all.”
On the contrary, not being philosophic costs us very dearly. If you feel you are separated (divisible), you may ultimately feel self-important, which would make your desires intense. If met with obstacle, such intense desire becomes anger, and if fulfilled such desire becomes greed, and make you feel more self-important. And cycle of never-fulfilling chase repeats with more force!
Ironically, JWs not only feel separated, but take delight in such separation and that too to the extent of taking delight even in shunning those who disagree with them!
