Famous quotes containing the words fundamental and/or domain:
“In a period of a people’s life that bears the designation “transitional,” the task of a thinking individual, of a sincere citizen of his country, is to go forward, despite the dirt and difficulty of the path, to go forward without losing from view even for a moment those fundamental ideals on which the entire existence of the society to which he belongs is built.”
—Ivan Sergeevich Turgenev (1818–1883)
“In the domain of Political Economy, free scientific inquiry meets not merely the same enemies as in all other domains. The peculiar nature of the material it deals with, summons as foes into the field of battle the most violent, mean and malignant passions of the human breast, the Furies of private interest.”
—Karl Marx (1818–1883)
