“In view of the dramatic effects that alternative representations may produce on search and recognition processes, it may seem surprising that the differential effects on inference appear less strong. Inference is largely independent of representation if the information content of the two sets of inference rules [one operating on diagrams and the other operating on verbal statements] is equivalent—i. e. the two sets are isomorphs as they are in our examples”

— Herbert A. Simon

“Traditional statistics is strong in devising ways of describing data and inferring distributional parameters from sample. Causal inference requires two additional ingredients: a science-friendly language for articulating causal knowledge, and a mathematical machinery for processing that knowledge, combining it with data and drawing new causal conclusions about a phenomenon.”

Judea Pearl (1936) Computer scientist

“It seems to me that whenever circumstances arise in the ordinary business of life in which, if two persons were ordinarily honest and careful, the one of them would make a promise to the other, it may properly be inferred that both of them understood that such a promise was given and accepted.”

“A model is a qualitative or quantitative representation of a process or endeavor that shows the effects of those factors which are significant for the purposes being considered. A model may be pictorial, descriptive, qualitative, or generally approximate in nature; or it may be mathematical and quantitative in nature and reasonably precise. It is important that effective means for modeling be understood such as analog, stochastic, procedural, scheduling, flow chart, schematic, and block diagrams.”

“Man set out on a two-thousand-year trial of a particular method of differentiation, adapting the structure of his mental processes, conscious and unconscious, to a certain general form. We need to consider only the most general characteristics of this form, and for the purpose of this analysis, there reduce to two. Thought may be either unitary or dualistic (since other pluralistic forms may be neglected), and it may be either process or static. These two pairs produce four combinations or types of thought: unitary-process, unitary-static, dualistic-process and dualistic-static. The first and the last are the most stable and common types; the unitary-static and dualistic-process forms are less frequent and may be regarded as anomalous forms appearing at times of transition.”

“We distinguish diagrammatic from sentential paper-and-pencil representations of information by developing alternative models of information-processing systems that are informationally equivalent and that can be characterized as sentential or diagrammatic. Sentential representations are sequential, like the propositions in a text. Diagrammatic representations are indexed by location in a plane. Diagrammatic representations also typically display information that is only implicit in sentential representations and that therefore has to be computed, sometimes at great cost, to make it explicit for use. We then contrast the computational efficiency of these representations for solving several. illustrative problems in mathematics and physics.”

“That man is the noblest creature may also be inferred from the fact that no other creature has yet contested this claim.”

The proof that man is the noblest of all creatures is that no other creature has ever denied it.

“It is difficult for the matter-of-fact physicist to accept the view that the substratum of everything is of mental character. But no one can deny that mind is the first and most direct thing in our experience, and all else is remote inference — inference either intuitive or deliberate.”

“Since reasoning, or inference, the principal subject of logic, is an operation which usually takes place by means of words, and in complicated cases can take place in no other way: those who have not a thorough insight into both the signification and purpose of words, will be under chances, amounting almost to certainty, of reasoning or inferring incorrectly.”

“A significant observation regarding… architectural representations is that each is of a different nature than the others. They are not merely a set of representations, each of which is an increasing level of detail than the previous one. Level of detail is an independent variable, varying within each architectural representation.”
