American philosopher
Eric Hoffer (25 July 1902 – 21 May 1983) was an American writer on social and political philosophy. His first book, The True Believer: Thoughts On The Nature Of Mass Movements (1951) is widely recognized as a classic on mass-movements and the psychological roots of fanaticism. Despite rising to fame with the success and popularity of his writings, he continued to work as a longshoreman until retiring at age 65.

A man is likely to mind his own business when it is worth minding. When it is not, he takes his mind off his own meaningless affairs by minding other people's business.
This minding of other people's business expresses itself in gossip, snooping and meddling, and also in feverish interest in communal, national, and racial affairs. In running away from ourselves we either fall on our neighbor's shoulder or fly at his throat. 2.10.
The enemy — the indispensible devil of every mass movement — is omnipresent. He plots both outside and inside the ranks of the faithful. It is his voice that speaks through the mouth of the dissenter, and the deviationists are his stooges. If anything goes wrong within the movement, it is his doing. It is the sacred duty of the true believer to be suspicious. He must be constantly on the lookout for saboteurs, spies and traitors.
