Definition
The fallacy of misplaced concreteness is Whitehead's name, as used in these books, for mistaking a useful abstraction or stabilized appearance for the whole concrete reality from which it was abstracted. The diagnosis targets the supposed self-sufficiency of bounded things, not their reality or the necessity of thought's abstractions. A stable form can be real while depending on ongoing process and relations.
Explanation
AB illustrates the error with the rock: its dependable thingness is a shorthand for a durable pattern of relations. Thought necessarily abstracts; the fallacy begins when that selective view is taken for the whole. AB then distinguishes its own route through Simondon from a canonical descent through Whitehead, even while acknowledging the diagnostic affinity.
RB2 explicitly names the same fallacy in its conclusion. Things do not disappear under the process reading; they are reinterpreted as relatively stable patterns sustained through flow, relation and repetition. RB3 repeats the named warning and answers an objection to relational ontology: it does not deny relata, but denies that relata must be primitive self-standing substances.
These passages warrant one diagnostic sense with three book-owned treatments. Related critiques of static pictures in PB and RB1 do not establish a local use of the named fallacy. The entry preserves Whitehead's attribution without making every process argument an endorsement of his complete metaphysics.
Scope and attribution
Direct named scope is AB, RB2 and RB3. The entry records the books' use of Whitehead's diagnosis, not an independent reconstruction of his philosophy. PB/RB1 remain reviewed contextual comparisons without named-entry credit.
AB — The Actual Book
AB names Whitehead's fallacy while affirming that both the rock's stable pattern and the need to abstract are real. The mistake is to take a bounded snapshot for the whole concrete process. The following passage explicitly locates the author's active process lineage through Simondon rather than canonical Whiteheadian descent.

RB1 — The Real Book, Volume I: The Possible Is Real
Source-verified occurrence; see the printed-page references below.
Occurrence locators: 2.
RB2 — The Real Book, Volume II: Becoming Is Being
RB2 explicitly names the fallacy and reinterprets stable things as flow-dependent patterns without making them disappear. The adjoining murmuration and organism examples show form as an achievement of activity. This direct witness expands the inherited AB-only scope.
Occurrence locators: 232, 290.
RB3 — The Real Book, Volume III: Murmurations
RB3 attributes the named fallacy to Whitehead and treats apparent things as coherent relational patterns. The explicit objection-and-reply is material: it denies primitive self-subsisting relata, not relata altogether. Existing Whitehead and structural-realist references retain their separate roles.
