"Men's live is a group live". …

Man’s Life is a Group-Life :
(i) It is correct to say that ‘Man’s Life is a Group-life,’ Man is born in a group, brought up in a group, plays in a group, even learns in a group, progresses in a group and generally dies in society - again a social group.
(ii) We all live in society and bound together through certain norms, values costoms and practices. ‘We’ very often say that we belong to a society, and as members we share, certain traditions, historical experiences - These experiences may be painful or full of pleasures. All these experiences are transmitted to us by the previous generations or the groups of the people.
(iii) No individual can fulfil all his requirements without society or social groups. Division of labour is also possible in a group. Some members of a group have to produce food, others have to weave clothes, some have to erect houses, and so on so forth.
(iv) If a man is united to fulfil his needs, he is also at war with others (in a group) in certain other context.
