Sourcepost

A specific instance of Source Sophism—a post or comment whose sole purpose is to demand sources in a way that exhausts or dismisses rather than inquires. The Sourcepost often appears reasonable: "source?" "citation needed." But its function is not to seek information; it's to cast doubt, shift burden, or end engagement. The Sourcepost is recognizable by its pattern: demand source, dismiss source, demand better source, repeat. It's a rhetorical move disguised as a request.

"Source?" he commented, and nothing else. Not engagement, not discussion—just the demand. Sourcepost: source as conversation-ender, citation as cudgel. He didn't want to know; he wanted to stop knowing."

Source Sophism

The use of source requirements in bad faith—demanding sources in ways designed to be impossible to satisfy, or dismissing every source provided with shifting criteria. Source Sophism begins with "source?" and then moves through endless objections: biased source, outdated source, not authoritative enough, not primary enough, not the right kind of source. The goal is not to evaluate sources but to exhaust the person providing them. It's sophistry with citations: using the appearance of rigor to avoid engagement.

"She provided a source. 'That's biased.' Another. 'Too old.' Another. 'Not peer-reviewed.' Another. 'Predatory journal.' Source Sophism: source as infinite regress, citation as exhaustion. No source would ever be good enough because good enough wasn't the point."

Reality Sophism

The use of "reality" as a rhetorical weapon—invoking reality to dismiss alternative perspectives, experiences, or frameworks. Reality Sophism treats one's own interpretation of reality as Reality Itself: "face reality" means "agree with me." The sophist doesn't engage other views; they declare them unreal. It's sophistry with ontology: using reality to police what can be said, thought, or believed.

"Your experience doesn't match reality. Reality Sophism: using 'reality' to dismiss experience. The speaker didn't engage what she felt; they just declared it unreal. Reality became a weapon, not a shared world. The sophistry is in the certainty: my reality is real; yours is not."

Truth Sophism

The use of "truth" as a rhetorical weapon—invoking truth to end discussion, dismiss opponents, or claim authority without justification. Truth Sophism treats "truth" as a possession, not a goal: "I have the truth" means "you have nothing to say." The sophist doesn't demonstrate truth; they assert it, using the word's power to silence. It's sophistry about truth: using the concept to avoid the work of finding it.

"I'm just interested in the truth, unlike you." Truth Sophism: using truth as a cudgel, not a compass. The claim to truth became a way to dismiss, not a way to inquire. Truth wasn't sought; it was asserted—and anyone who disagreed was against truth itself."

Debate Sophism

A specific form of Argumentative Sophism focused on formal debate tactics—using debate rules, formats, and expectations to gain advantage rather than find truth. Debate Sophism treats every exchange as a contest to be won, using rhetorical tricks, strategic ambiguity, and procedural objections to dominate opponents. The sophist knows debate's rules and exploits them, turning what could be dialogue into performance.

"He objected to the format, then to the timing, then to the moderator. When the debate finally started, he spent his time questioning premises, not addressing arguments. Debate Sophism: using debate's procedures to avoid debate's purpose. The game was the point; truth was irrelevant."

Argumentative Sophism

The use of argumentation itself in bad faith—treating debate as combat, not inquiry, and using the forms of argument to avoid substance. Argumentative Sophism includes endless questioning (sealioning), moving goalposts, demanding definitions, and other tactics that use the appearance of argument to prevent actual argument. The sophist doesn't want to find truth; they want to win, exhaust, or dominate. Argument becomes performance, not dialogue.

"He asked for definitions, then redefined them. He demanded evidence, then dismissed it. He posed questions, then ignored answers. Argumentative Sophism: using the forms of debate to destroy the possibility of debate. The goal wasn't understanding; it was winning—and winning meant the other side gave up."

Empirical Sophism

The use of empiricism in bad faith—demanding empirical evidence for things that cannot be empirically accessed, or dismissing non-empirical knowledge as worthless. Empirical Sophism treats "empirical" as a magic word that ends inquiry: if it's not measurable, it's not real. The sophist ignores that empiricism itself is a philosophical position, not a self-evident truth, and that many important domains (ethics, mathematics, experience) resist empirical methods. It's sophistry in a lab coat: using science's prestige to dismiss everything outside science.

"You can't prove consciousness empirically, so it must be illusion. Empirical Sophism: demanding empirical evidence for the very condition of having experience. The demand is absurd, which is the point. Empiricism becomes a weapon against the empirical world's own foundations."
