“Ars” came to be laden with specific meaning in the intellectual culture of late-Republican Rome, with some artes being regarded as intellectually and socially worthier than others. These “higher artes” were distinguished by several features that would form the premises for the scientific culture of the artes in the early Roman Empire. These premises were established in Rome by the reception of Greek notions of technê (τέχνη) but were elaborated independently and joined for the first time into a unified conception of specialized knowledge by Roman thinkers, including Cicero and Varro. The higher artes are logically organized and systematically presented, hence systematic. They are related to one another in their principles and methods, hence interdisciplinary. They entail explanatory knowledge of their methods in terms of causes in nature, and are hence explanatory. And they balance experience and practical know-how with theoretical knowledge, and are hence balanced.
