Satyendra Bose had doubts in his mind that, "are changes helpful in life?”. To answer his question, Aristotle asked him to classify following changes into helpful and non-helpful from their perspective. (NA denotes Not Applicable)
1. Farmers harvesting crop
2. Ripening of Fruits
3. Rancidity of food
Helpful change - 1, 2; Non-Helpful Change - 3
1.The farmers harvesting crop is helpful as the crop after processing becomes grain, which is essential for nutrition and survival.
2.Ripening of Fruits is a helpful change as fruits become sweeter after it ripens and so becomes tastier.
3.Rancidity of food is non-helpful as food becomes stale and not suitable for consumption.
Hence all changes are not helpful.
