John Henry Holland: Frasi in inglese

“Model building is the art of selecting those aspects of a process that are relevant to the question being asked.”

John H. Holland

Origine: Hidden Order - How Adaptation Builds Complexity (1995), Ch 4. Simulating Echo, p. 146
Contesto: Model building is the art of selecting those aspects of a process that are relevant to the question being asked. As with any art, this selection is guided by taste, elegance, and metaphor; it is a matter of induction, rather than deduction. High science depends on this art.

“High science depends on this art.”
