Information: Any difference that makes a difference [Interface This general term for a surface that forms the meeting place between two regions serves to replace the notion of boundary when speaking in three dimensions. In GB‘s usage, dealing with the interaction of systems that may not be entirely enclosed or bounded, it typically refers to system boundaries defined by information exchange and by changes in coding, rather than to enclosures like skin. As such, ―interface‖ becomes the term for the locus of systemic interaction.]
[Learning: GB included within the notion of ―learning‖ all those events in which a system responds to some external stimulus, including as a limiting case examples in which the system adjusts but is unchanged (e.g. a thermostat switching on the heat in response to falling temperature: zero learning), but focusing on those cases in which the system is modified in response to the information received. The concept thus becomes an umbrella concept to include adaptation, character formation,, habituation, acclimation, addiction, etc., as well as more familiar forms of learning, and can refer to different logical types. Notably, learning in which the learning capacity of the system is modified (―deutero - learning‖) is referred to as learning II, being of a higher logical type than learning in which the organism is changed without an alteration in learning capacity.] Linear and lineal: ―Linear is a technical term in mathematics describing a relationship between variables such that when they are plotted against each other on ―orthogonal Cartesian coordinates, the result will be a straight line. Lineal‖ describes a relation among a series of causes or arguments such that the sequence does not come back to the starting point. Logical types : A series of examples is in order: 1. The name is not the thing named but is of different logical type, higher than that of the thing named. 2. The class is of different logical type, higher than that of its members. 3. The injunctions issued by, or control emanating from, the bias or the house thermostat is of higher logical type than the control issued by the thermometer. (The ―bias‖ is the device on the wall that can be set to determine the temperature around which the temperature of the house will vary.) 4. The word ―tumbleweed‖ is of the same logical type as ―bush‖ or ―tree.‖ It is not the name of a species or genus of plants; rather, it is the name of a [[p_210]] class of plants whose members share a particular style of growth and dissemination. 5. ―Acceleration‖ is of higher logical type than ―velocity.‖ [ Metalogue : A metalogue is a conversation dealing with some aspect of mental process in which ideally the interaction exemplifies the subject matter.] [ Metaphor : Strictly, a literary device in which a description is extended from some item to another with which it shares certain characteristics. Sometime contrasted with ―simile‖, in which comparison is explicit, whereas metaphor, by not making comparison explicit, proposes a degree of identity. For GB, metaphor includes all processes of knowing and communicating that depend

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
