Tertium non datur

Tertium non datur is the Latin expression John Spooke invokes to frame difficult questions as choices between two alternatives. In the discussion, it becomes both a compact logical rule and a recurring verbal signature: John uses it to press the group toward definite answers, even when the questions themselves remain unsettled.

Meaning and Use

The expression means that there is no third possibility. John first applies this either-or structure to the question of extraterrestrial life: life exists elsewhere in the Universe, or it does not. The moderator acknowledges that either answer could be correct, since life might be abundant beyond Earth or confined to the planet, and that both possibilities can leave the group perplexed.

The exchange distinguishes the clarity of the alternatives from certainty about which one is true. The moderator says that four people at the table have given a correct and precise answer, but does not identify them. When Mario objects that the group has not been told who answered correctly, the moderator replies that this does not matter; what matters is that four people have answered the question correctly. The formula therefore organizes the debate without disclosing its resolution.

John Spooke’s Refrain

John extends the same pattern across a series of cosmological and metaphysical questions. He asks whether cosmic energy has always existed, and, if not, whether it arose spontaneously or through an act of creation from outside or within. He asks whether the Universe will keep expanding or contract and give rise to successive Big Bangs and new universes, whether transcendental consciousness exists or only the physical Universe, and whether a human soul survives the brain’s death or all natural things are equally transient. He also asks whether supernatural phenomena are real or remnants of mythical or animistic thinking.

As the group divides into opposing camps, John repeatedly cautions that at least some participants have answered correctly; not once does everyone agree. He punctuates these divisions by shouting “¡Una cosa u otra!” and sealing his second-degree equations with the Latin incantation “Tertium non datur!” The refrain makes the structure of the gathering audible: questions are posed as alternatives, answers split the room, and unanimity never arrives.

Rhetorical and Narrative Function

The expression gives John’s questioning a brisk, almost ceremonial force. Its Latin form turns a rule of logic into a verbal flourish, while the moderator’s refusal to name the four correct respondents preserves uncertainty about the answerers even as he insists that some answers are right. The discussion thus separates the existence of a determinate answer from the group’s ability to discover or agree on it.

After the exchange, two bottles of champagne are brought to the table at Bill’s request, and the conversation shifts into a new phase: everyone is invited to present a brief view of life. The gathering moves from John’s repeated binary questions to personal worldviews, beginning with José’s argument that the Universe had to be vast and physically suitable enough to produce human beings. Tertium non datur marks the debate’s governing rhythm, but does not settle the larger questions it raises.
