p.78 it will be asserted that an organism does not even just perceive, rather it always goes still further and "propositionalizes."

 p.80 Discriminanda is my name for those properties of objects wherein, in purely sensory fashion, such objects differ from another. [JLJ - sense qualities]

p.81 Discriminanda expectations, on the other hand, are the cognitive sets or determinants aroused in the individual organism on the given occasion. [JLJ - resultant sensations]

p.82 By manipulanda I would understand those properties of objects which actually support (i.e., make possible) motor manipulations.

p.83 Manipulanda expectations, like discriminanda expectations, are sets or preparations aroused in the organism, which may or may not be confirmed and supported by the actual entities truly present then and there in the environment.

p.85-86 By means-end relations I wish to designate those interrelational properties between environmental objects, whereby the "enjoyment of" (i.e., the "commerce with") the discriminanda and manipulanda constitutive of one such object will (or will not) actually lead on to an immediate possibility of "enjoyment of" (commerce with) the discriminanda and manipulanda of such and such other environmental objects.

p.86 An organism immersed in his environment comes into contact at a given moment with a certain group of stimuli... The environment as so envisaged is thus naught but a very field or tissue of means-end relations. It is a means-end field in which the various component objects and situations appear ineluctably in their roles of possible, or impossible, good, or bad, better or worse, means to, or from, such and such other objects or situations.

[JLJ - Tolman touches on the idea of the predicament and its central position in our efforts to determine how to 'go on.' Our attention is drawn to the predicament out of necessity, and to the various cues which we have pre-decided to have meaning, and to the execution of our present scheme to 'go on' within it. We are constantly distracted by various things and events, but we eventualy ask 'how much should I care about that?" and our thought promptly returns to our predicament - to our situational awareness scanning and to our diagnostic tests which inform us on how things are going - and how we can scheme to leverage events to resolve in our favor, in both near and distant points in the future.]
