TRUTH IS VERY HARMFUL FOR SURVIVAL

No one like the truth.Truth assault to our identity.We love to our identity more than our life.If our identity dead there is no meaning to our living.Man live on hope hope is another name of illusion.Truth always destroy our hope.If you tell the truth you will create many enemies.Hope is the sheet anchor of every man.When hope is destroyed, great grief follows ,which is almost equal to death itself. Never speak to truth to anybody, create a hope, manipulate truth and create illusion you can get more money, prestige and you will be happy. Truth only lead to you unhappiness.

What purpose man live?

Darwin evolution telling us man live for survival and reproduction.In Reproduction I include Art, Music,literature,philosophy and all other creating work.Survival is so much open in every creature so there is no controversy on this issue.
There are lot of contraversy on reproduction.All animal including man,production mean give birth to next generation.This reproduction are doing by all living creature including plants.This vague defination.I think we must include art, music,literature and other creation which have some permentant value is reproduction. Many philosophers arists were unmarried but the reproducted manument work.
My question is can man have no other motive other than reproduction? Same question raised by Richard Dawkkins in his book The Selfish Gene but it is quite different connection He say"We are build as gene machine and cultured as meme machine,butwe have the power to turn agianst our creators. We alone on earth can rebel against the tyranny of selfish replicators. But HOW?
This question is tormenting to me fromlong long time. Can anybody have answer?
