Famous Robert Rosen Quotes

“I do not consider myself a philosopher. I am a biologist, attempting to grapple with the Schrodinger question, “What is Life?” It turns out that this is not an empirical question, to be resolved through observation in a laboratory.”

Rosen, Robert. " On the limitations of scientific knowledge http://www.synapse9.com/ref/Rosen_On_Limitations_of_Sci.pdf." Boundaries and barriers: On the limits to scientific knowledge, Reading, MA: Perseus Books (1996): 199-214.

“The physical structures of organisms play only a minor and secondary role… The only requirement which physical structure must fulfill is that it allow the characteristic behaviors themselves to be manifested. Indeed, if this were not so, it would be impossible to understand how a class of systems as utterly diverse in physical structure as that which comprises biological organisms could be recognised as a unity at all.”

Robert Rosen. "Anticipatory systems in retrospect and prospect," in: General Systems, Vol. 24 (1979), p. 12; AS cited in: Nadin, Mihai. " Anticipation and dynamics: Rosen's anticipation in the perspective of time http://www.nadin.ws/archives/966." International journal of general systems. 39.1 (2010): 3-33.

“Perhaps the first lesson to be learned from biology is that there are lessons to be learned from biology.”

Robert Rosen (2013), Essays on Life Itself Chapter 18

“Let us begin by observing that the word "system" is almost never used by itself; it is generally accompanied by an adjective or other modifier: physical system; biological system; social system; economic system; axiom system; religious system; and even "general" system. This usage suggests that, when confronted by a system of any kind, certain of its properties are to be subsumed under the adjective, and other properties are subsumed under the "system," while still others may depend essentially on both. The adjective describes what is special or particular; i. e., it refers to the specific "thinghood" of the system; the "system" describes those properties which are independent of this specific "thinghood."
This observation immediately suggests a close parallel between the concept of a system and the development of the mathematical concept of a set. Given any specific aggregate of things; e. g., five oranges, three sticks, five fingers, there are some properties of the aggregate which depend on the specific nature of the things of which the aggregate is composed. There are others which are totally independent of this and depend only on the "set-ness" of the aggregate. The most prominent of these is what we can call the cardinality of the aggregate…
It should now be clear that system hood is related to thinghood in much the same way as set-ness is related to thinghood. Likewise, what we generally call system properties are related to systemhood in the same way as cardinality is related to set-ness. But systemhood is different from both set-ness and from thinghood; it is an independent category.”
