▁satisf iers ▁ ▁If ▁we ▁take ▁a ▁look ▁at ▁satisf iers ▁for ▁the ▁needs ▁of ▁the ▁community , ▁a ▁distinction ▁can ▁be ▁made ▁between ▁ex ogen ous ▁and ▁end ogen ous ▁satisf iers . ▁ ▁End ogen ous ▁satisf iers ▁arise ▁from ▁actions ▁of ▁the ▁community ▁at ▁the ▁basic ▁level ▁(' syn erg istic ▁satisf iers '). ▁They ▁are ▁anti - author itar ian ▁and ▁may ▁contribute ▁to ▁Human ▁Sc ale ▁Development . ▁Even ▁though ▁in ▁some ▁cases ▁they ▁are ▁part ▁from ▁processes ▁that ▁are ▁propag ated ▁by ▁the ▁state . ▁For ▁example , ▁self - managed ▁production ▁satisfies ▁the ▁need ▁for ▁subs istence , ▁but ▁also ▁is ▁helpful ▁in ▁the ▁needs ▁of ▁understanding , ▁participation ▁and ▁creation . ▁ ▁Ex ogen ous ▁satisf iers ▁are ▁usually ▁im posed , ▁induced , ▁rit ual ized ▁or ▁institution al ized . ▁They ▁arise ▁at ▁the ▁top ▁( in ▁the ▁sense ▁of ▁a ▁political ▁group ▁or ▁traditional ▁power - hold ers ) ▁and ▁are ▁im posed ▁on ▁everyone , ▁and ▁prevent ▁Human ▁Sc ale ▁Development . ▁There ▁are ▁several ▁categories ▁of ▁ex ogen ous ▁satisf iers . ▁▁ ▁They ▁derive ▁from ▁co erc ion ▁(' vi ol ators '). ▁They ▁destroy ▁in ▁the ▁long ▁term ▁the ▁possibility ▁to ▁satisfy ▁this ▁need ▁in ▁this ▁way . ▁They ▁also ▁prevent ▁the ▁possibility ▁of ▁satisfying ▁other ▁needs . ▁They ▁lead ▁to ▁devi ant ▁human ▁behavior . ▁Fail ure ▁to ▁comp ly ▁with ▁such ▁satisf iers ▁leads ▁to ▁fear . ▁For ▁example ▁arms ▁race ▁and ▁b ureau c racy
