  7. Here one of the most famous statements Einstein made about this issue: “I never belonged to any nation or country with all my heart, to any group of friends, not even to my own family. These ties were always accompanied with a vague detachment, and a desire to withdraw inside myself increases with the years passing. Sometime this isolation feels bitter, but I do not regret to be cut away from understanding and sympathy of the other humans. Surely, this behaviour makes me lose something, but it rewards me with being independent on others’ customs, opinions and prejudices, and I do not feel tempted to establish my peace of mind on such weak foundations.” op. cit., p. 3.
