EigoPro 準1級読解 — The Puzzle of Free Will

Few questions feel as intimate as whether our choices are truly our own. When you decide to read this sentence rather than close the page, the decision seems to originate within you, unforced and freely made. Yet a growing chorus of neuroscientists insists that this feeling is a kind of elaborate illusion. In a series of celebrated experiments, researchers detected patterns of brain activity that preceded a subject's conscious awareness of having decided to move—sometimes by several seconds. If the brain commits to an action before "you" know about it, the argument runs, then the conscious self is less an author than a spectator, narrating decisions it did not actually make. This conclusion, however, may rest on a sleight of hand. Critics point out that pressing a button in a laboratory is a trivial, arbitrary act, nothing like the deliberation that precedes a career change or a moral stand. To leap from twitching a finger to the whole architecture of human agency is, they contend, to mistake a fragment for the entire structure. Moreover, the very notion of freedom that the experiments seem to demolish—an uncaused self standing outside the causal order—is one that few serious philosophers have ever defended. A more durable position, known as compatibilism, sidesteps the impasse altogether. On this view, freedom does not require an escape from causation; it requires only that our actions flow from our own reasons, desires, and character, rather than from coercion or compulsion. A person who reflects, weighs alternatives, and acts accordingly is free in every sense that matters, even if that deliberation is itself the product of prior causes. The debate, then, may turn less on new data than on what we mean by the word "free." And that, in the end, is a question no brain scan can settle.

問 1

What is the main idea of the passage?

Neuroscience and philosophy will never have anything useful to say to each other.
Whether neuroscience disproves free will depends largely on how the term "free" is defined.
Recent brain experiments have conclusively proven that free will does not exist.
People should stop believing that their everyday choices matter at all.

Phrase

The debate, then, may turn less on new data than on what we mean by the word "free."

⚡ひとことで

本文全体は「自由意志を神経科学が否定したかは『自由』の定義次第」という論旨。

選択肢の解説Choice Analysis

「Whether neuroscience disproves free will depends largely on how the term "free" is defined.」

正解

本文は (1) 脳活動が意識的決定に先行する実験→ (2) その解釈への批判→ (3) 両立論 (compatibilism) という構成で、最終段に The debate ... may turn less on new data than on what we mean by the word "free" と結論する。よって「神経科学が自由意志を否定するかは『自由』の定義に大きく依存する」が主旨。

「Recent brain experiments have conclusively proven that free will does not exist.」
= 脳実験が自由意志の非存在を決定的に証明した ━ 本文は実験の結論を sleight of hand (まやかし) と疑問視しており『決定的に証明』とは言っていない。
「Neuroscience and philosophy will never have anything useful to say to each other.」
= 神経科学と哲学は互いに無益 ━ 両分野を対立させてはいるが『永遠に無益』という極端な主張はしていない。
「People should stop believing that their everyday choices matter at all.」
= 日常の選択は無意味だと信じるべき ━ 本文はむしろ意味ある自由 (free in every sense that matters) を擁護しており正反対。

▦Collocation

パターン	意味	例
turn on ~	~次第である／~にかかっている	The debate turns on the definition.
less A than B	AというよりむしろB	less on data than on meaning
rest on a sleight of hand	まやかしに依拠する	The conclusion rests on a sleight of hand.
in the end	結局のところ	In the end, it is a question of meaning.
settle a question	問題に決着をつける	No scan can settle the question.

❝例文

The outcome turns on how we define success.
結果は成功をどう定義するか次第だ。
It is less a matter of money than of trust.
それは金よりむしろ信頼の問題だ。
No experiment can settle a purely conceptual dispute.
純粋に概念的な論争に実験で決着はつかない。

💡Tip · 覚えるコツ

主旨設問は最終段の結論文 (often 'in the end' / 'then' 付き) を探すと速い。本文は『データではなく定義の問題』という枠組み転換が核心。

問 2

According to the passage, what did the celebrated experiments detect?

Brain activity that occurred only after a subject had finished moving.
Brain activity that came before a subject was consciously aware of having decided to move.
A complete absence of brain activity during simple decisions.
Identical brain patterns in subjects making trivial and moral decisions.

Phrase

patterns of brain activity that preceded a subject's conscious awareness of having decided to move

実験が検出したのは『意識的に決めたと気づく前』に現れる脳活動。

選択肢の解説Choice Analysis

「Brain activity that came before a subject was consciously aware of having decided to move.」

正解

第1段で researchers detected patterns of brain activity that preceded a subject's conscious awareness of having decided to move—sometimes by several seconds と述べる。precede (先行する) を came before に言い換えた「被験者が動こうと決めたと意識する前に現れた脳活動」が正解。

「Brain activity that occurred only after a subject had already finished moving.」
= 動作完了後にのみ生じた脳活動 ━ 本文は『先行する (preceded)』であって『後』ではないので逆。
「A complete absence of any brain activity at all during the simplest decisions.」
= 単純な決定中の脳活動の完全な欠如 ━ 活動の検出が論点で『欠如』は本文にない。
「Identical brain patterns in subjects making both trivial and moral decisions.」
= 些細な決定と道徳的決定で同一の脳パターン ━ 本文はむしろ両者を区別 (button vs moral stand) しており同一とは述べていない。

▦Collocation

パターン	意味	例
precede ~	~に先行する	Activity preceded awareness.
conscious awareness of ~	~についての意識的自覚	awareness of having decided
commit to an action	行動に踏み切る	The brain commits to an action.
by several seconds	数秒だけ	preceded by several seconds
detect a pattern	パターンを検出する	Researchers detected patterns.

❝例文

The warning preceded the crash by a few seconds.
警告は衝突の数秒前に出た。
She had no conscious awareness of the decision.
彼女はその決定を意識的に自覚していなかった。
The system commits to a choice before the user notices.
システムはユーザーが気づく前に選択に踏み切る。

💡Tip · 覚えるコツ

detail 設問は本文の動詞を別語に置換した選択肢が正解になりやすい (preceded→came before)。時間の前後 (before/after) を入れ替えた誤答に注意。

問 3

How does compatibilism define freedom?

As acting from one's own reasons and character rather than from coercion, even within a causal order.
As proof that the conscious self never influences any action.
As the ability to make decisions that have no prior causes whatsoever.
As the freedom that only exists in trivial laboratory tasks.

Phrase

freedom does not require an escape from causation; it requires only that our actions flow from our own reasons, desires, and character

⚡ひとことで

両立論=自由とは因果からの脱出ではなく、自分の理由・性格から行為が生じること。

選択肢の解説Choice Analysis

「As acting from one's own reasons and character rather than from coercion, even within a causal order.」

正解

第3段で compatibilism を freedom does not require an escape from causation; it requires only that our actions flow from our own reasons, desires, and character, rather than from coercion or compulsion と定義する。これを言い換えた「強制ではなく自らの理由・性格から行為すること、因果の中であっても」が正解。

「As the ability to make decisions which have no prior causes of any kind at all whatsoever.」
= 一切の先行原因を持たない決定をする能力 ━ 本文はこの『因果からの脱出』こそ両立論が不要とする立場なので逆。
「As proof that the conscious self never once influences any single one of our actions at all.」
= 意識的自己が行為に一切影響しない証拠 ━ 両立論は熟慮し行為することを自由と認めており影響を否定していない。
「As the kind of freedom that only ever exists within the trivial tasks of a laboratory.」
= 些細な実験課題でのみ存在する自由 ━ 本文に該当する記述はなく、実験批判の文脈の混同。

▦Collocation

パターン	意味	例
require an escape from ~	~からの脱出を必要とする	It does not require an escape from causation.
flow from ~	~から生じる	Actions flow from our reasons.
rather than ~	~ではなく	from reasons rather than coercion
weigh alternatives	選択肢を比較検討する	She weighs alternatives and acts.
the product of prior causes	先行する原因の産物	deliberation is the product of prior causes

❝例文

A free choice flows from one's own values.
自由な選択は自らの価値観から生じる。
He acted from conviction rather than fear.
彼は恐れではなく信念から行動した。
Her decision was the product of long deliberation.
彼女の決定は長い熟慮の産物だった。

💡Tip · 覚えるコツ

定義設問は本文の『A does not require X; it requires only Y』構文の Y を捉える。否定された X (escape from causation) を正解にすり替えた誤答に注意。
