Scientists, poets, anglers and philosophers forget prosaic things. Their minds are absorbed in lofty thoughts and glorious imaginations that they forget ordinary things. Socrates, Tagore and Einstein had the virtue of absent – mindedness. Einstein usually forgot to change his rocks. Once he even forgot his own house address. The absent – mindedness of such great personalities is a virtue. As they make best of life, they have no time to remember the mediocre.
