inheritance: late 14c., enheritaunce “fact of receiving by hereditary succession;” early 15c. as “that which is or may be inherited,” from Anglo-French and Old French enheritaunce, from Old French enheriter “make heir, appoint as heir.” The meaning of “genetically deriving a quality, characteristic, or predisposition, from one’s parents or ancestors” is definitely after Gurdjieff’s time.

It helps to fix this in the mind when reading The Tales. When Gurdjieff uses the word “inheritance” he’s usually referring to habits acquired by imitating one’s parents or grandparents, or possibly habits one acquired earlier in one’s life.
