Definition
Contingency names the dependence of actual outcomes on events and conditions that could have been otherwise, rather than on a predetermined destination. The books develop this through evolutionary history, constrained actualization and historical lock-in. RB2 extends the question to law-regimes themselves. Neither contingent outcomes nor contingent laws are thereby arbitrary, and statistical direction need not determine particular histories.
Explanation
AB follows Gould in rejecting evolution as a ladder toward humanity, while insisting that existing organization channels novelty. RB1 presents Gould's replay argument alongside Conway Morris's convergence thesis and LIFI's proposed accumulation of functionally successful forms. Its point is not that contingency abolishes regularity: particular lineages and timings can remain contingent while broader tendencies recur under specified conditions.
A second use concerns genuine openness rather than ignorance. RB1 describes actualization as historically specific selection among structured possibilities. RB3 distinguishes microscopic contingency from aggregate directional bias and explains historical lock-in through sequence and timing. Its physical discussion qualifies macroscopic ontic openness as inherited from quantum indeterminacy on the interpretation adopted, not a new randomness generated merely by complexity.
RB2 asks whether laws themselves could have been otherwise. Meillassoux supplies the denial of eternal necessity, but the author tempers radical contingency with stabilization: law-regimes are historical achievements, not arbitrary choices. The discussion explicitly makes evolving laws philosophically intelligible rather than claiming to have proved them. This stronger modal question remains distinct from the contingency of events within a regime.
Scope and attribution
Positive treatments belong to AB, RB1, RB2 and RB3. PB's general open and creative becoming does not by itself establish this entry's historical or modal treatment. Sensorimotor contingencies are separately indexed, not an alias.
AB — The Actual Book
Evolution could have branched otherwise and is not directed toward humans. Real openness remains channeled by existing organismal organization.
Occurrence locators: 48, 49, 53, 54, 209; Thinker register: 229; Notes: 239.
RB1 — The Real Book, Volume I: The Possible Is Real
Unique historical circumstances are contrasted with convergence and LIFI's conditional trends. Actualization is also treated as constrained historical resolution. Simondon's contingency is not assigned Kastner's probability calculus.
Occurrence locators: 103, 108, 110, 113, 118, 120, 144, 166, 172, 173, 175, 176, 177, 219, 220, 223, 226, 244, 247, 249, 250, 257, 262, 276, 284.
RB2 — The Real Book, Volume II: Becoming Is Being
Law-regimes may be contingent historical achievements. Meillassoux opposes eternal necessity, but constraints stabilize rather than laws being arbitrary. Evolving laws are rendered coherent, not physically proved.
Occurrence locators: 264, 266, 267, 268, 269, 276, 293; Notes: 260, 261.
RB3 — The Real Book, Volume III: Murmurations
Timing and lock-in constrain later options without foreordaining particular outcomes. Macroscopic contingency is ontically open only insofar as it inherits quantum openness on the adopted reading. FN155 makes amplification, not a universally single seed, the relevant constant.
