"The rehabilitation of order as a universal principle, however, suggested at the same time that orderliness by itself is not sufficient to account for the nature of organized systems in general or for those created by man in particular"

This quote by Rudolf Arnheim suggests that order alone is inadequate to discuss the intricacy of organized systems, both natural and man-made. He is indicating that there is more to the structure of these systems than simply order. He is suggesting that there is a need for rehab of order as a universal concept, meaning that order needs to be seen as a fundamental part of any system, however it ought to not be the only aspect taken into account. Arnheim is suggesting that order is necessary, but it is insufficient to explain the intricacy of organized systems. He is suggesting that there is a requirement to look beyond order and think about other elements such as imagination, innovation, and intricacy. By doing so, we can gain a much better understanding of the nature of arranged systems and how they are created.
