"A semantic definition of a particular set of command types, then, is a rule for constructing, for any command of one of these types, a verification condition on the antecedents and consequents."

"If the advancement of the general art of programming requires the continuing invention and elaboration of paradigms, advancement of the art of the individual programmer requires that he expand his rep…"

"It is, therefore, possible to extend a partially specified interpretation to a complete interpretation, without loss of verifiability, This fact offers the possibility of automatic verification of pro…"

"For having a clear influence on methodologies for the creation of efficient and reliable software, and for helping to found the following important subfields of computer science: the theory of parsing…"

"If there is ever a science of programming language design, it will probably consist largely of matching languages to the design methods they support."

"The establishment of formal standards for proofs about programs and the proposal that the semantics of a programming language may be defined independently of all processors for that language, by estab…"

"To the designer of programming languages, I say: unless you can support the paradigms I use when I program, or at least support my extending your language into one that does support my programming met…"

"Although my own previous enthusiasm has been for syntactically rich languages like the Algol family, I now see clearly and concretely the force of Minsky's 1970 Turing lecture, in which he argued that…"
