plasticism

The life of ants is crowded with such socialphychological corrections which regulate the mechanism of instinct by individual “plasticisms,” conduct it into useful paths, and thus bring about an adaptation to external advantages and disadvantages.

The New York plasticism will be also the plasticism of Paris and Petrograd.

Such an individual will almost certainly have noticed by this time a kind of creeping plasticism in the clothes he wears, the appliances he uses, the furniture he sits on, the car he drives and possibly even the house he lives in.
