Is it? I remember having read an essay with this title long back, when I was in school. I have forgotten the name of the author but it was a great name. One of the arguments he gave supporting the assertion was that how difficult it would be to pass time, or to live if we knew that we are going to die on a given date/time! Although we know that one day we have to do die, the ignorance of the exact date and time makes it a non relevant information. I agree with the author that knowing exact time would make our lives (for most people) really miserable.
Yet, like all “truth” this is also true only relatively. Ignorance compared with general knowledge cannot be bliss. Ignorance about the food that we eat can lead to disaster. While ignorance about the existence (or otherwise) of God may not really harm us bot ignorance about the ill effects of tobacco/alcohol can play havoc with our health and life and relationships! Ignorance about the emotional status of our near and dear ones can ruin the relationships and social fabric. Knowledge may not provide as much power as is believed but it does give us a chance to take relevantly wise decisions. Remember the earlier ignorance about the nature and natural events like rain and earthquake! Knowledge has made our life comfortable . No?
So let us try to to gain knowledge without believing the knowledge is the panacea for our problems. Ignorance mat really be bliss in some cases! Gain knowledge to know which ignorance is Bliss. GOD BLESS ALL!
