Satyendra Bose had doubts in his mind that, "are changes helpful in life?”. To answer his question, Aristotle asked him to do an activity. He asked the student to classify following changes into helpful and non-helpful from their perspective. (NA denotes NotApplicable)
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.
