Particular individuals do not recur, but their building blocks do. — John Henry Holland Block Copy Share Image
nonlinear interactions almost always make the behavior of the aggregate more complicated than would be predicted by summing or averaging. — John Henry Holland Behavior Copy Share Image
The multiplier effect is a major feature of networks and flows. It arises regardless of the particular nature of the resource, be… — John Henry Holland Arise Copy Share Image
Model building is the art of selecting those aspects of a process that are relevant to the question being asked. As with… — John Henry Holland Art Copy Share Image
When a new building block is discovered, the result is usually a range of innovations. — John Henry Holland Block Copy Share Image
Evolution continually innovates, but at each level it conserves the elements that are recombined to yield the innovations. — John Henry Holland Biology Copy Share Image
The recycling of resource by the aggregate behavior of a diverse array of agents is much more than the sum of the… — John Henry Holland Action Copy Share Image
Unwrapping occurs when the "solution" is explicitly built into the program from the start. — John Henry Holland Built Copy Share Image
