Context and Key Positions<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Sense-data<\/strong>&nbsp;are often invoked by foundationalists (e.g., Russell, Ayer) as the basis of empirical knowledge, while anti-foundationalists (e.g., Rorty, Bonjour) reject them.<\/li>\n\n\n\n<li><strong>Chisholm<\/strong>&nbsp;is an exception: a foundationalist who rejects sense-data, arguing that the&nbsp;<strong>sense-datum inference<\/strong>&nbsp;(from &#8220;appears&#8221; language to the existence of sense-data) is fallacious.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. The Sense-Datum Inference<\/strong><\/h3>\n\n\n\n<p>Chisholm formulates the inference in multiple ways, all of which move from statements about how things appear (e.g., &#8220;X appears F&#8221;) to claims about the existence of appearances (e.g., &#8220;There is something F&#8221;). For example:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><em>M appears P to S; therefore, something is P.<\/em><\/li>\n\n\n\n<li><em>M appears P to S; therefore, there is an appearance which is P.<\/em><\/li>\n<\/ol>\n\n\n\n<p>Chisholm attacks this inference as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Deductively invalid<\/strong>&nbsp;(due to counterexamples).<\/li>\n\n\n\n<li><strong>Inadvisable<\/strong>&nbsp;(it multiplies entities and creates metaphysical problems, like the speckled hen).<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Chrucky\u2019s Critique<\/strong><\/h3>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>A. Ambiguity in &#8220;Appears&#8221; Statements<\/strong><\/h4>\n\n\n\n<p>Chrucky argues Chisholm conflates distinct uses of &#8220;appears&#8221;:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Epistemic<\/strong>&nbsp;(&#8220;appeare&#8221;): Expresses belief (e.g., &#8220;It seems that X is F&#8221;).<\/li>\n\n\n\n<li><strong>Comparative<\/strong>&nbsp;(&#8220;appearc&#8221;): Compares to typical cases (e.g., &#8220;X looks like F-things usually do&#8221;).<\/li>\n\n\n\n<li><strong>Noncomparative<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>Ostensible<\/strong>&nbsp;(&#8220;appearo&#8221;): Reports perceptual content without commitment to truth (e.g., &#8220;X ostensibly looks F&#8221;).<\/li>\n\n\n\n<li><strong>Phenomenal<\/strong>&nbsp;(&#8220;appearp&#8221;): Describes raw sensory qualities (e.g., color, shape).<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n<p>Chisholm\u2019s counterexamples (e.g., &#8220;The pail feels empty&#8221;) rely on&nbsp;<strong>non-phenomenal<\/strong>&nbsp;uses of &#8220;appears,&#8221; but the sense-datum inference hinges on the&nbsp;<strong>phenomenal<\/strong>&nbsp;use (e.g., &#8220;The curtain appears green&#8221;). Thus, his counterexamples miss the mark.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>B. Defense of the Phenomenal Use<\/strong><\/h4>\n\n\n\n<p>Chrucky (following Jackson) defends the&nbsp;<strong>irreducibility<\/strong>&nbsp;of phenomenal appearances against reductionist attacks (e.g., Bennett\u2019s comparative analysis, Armstrong\u2019s counterfactual epistemic analysis). He sides with Chisholm\u2019s earlier view that phenomenal talk is distinct and tied to Aristotelian &#8220;proper sensibles&#8221; (color, shape, etc.).<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>C. Validity of the Inference<\/strong><\/h4>\n\n\n\n<p>For&nbsp;<strong>phenomenal<\/strong>&nbsp;cases (e.g., &#8220;The curtain appears green&#8221;), the inference to &#8220;There is a green appearance&#8221; is valid. Chisholm\u2019s objection\u2014that &#8220;something&#8221; reifies appearances\u2014can be addressed by interpreting &#8220;something&#8221; transcendentally (not as an external object).<\/p>\n\n\n\n<p>Chrucky concludes that Chisholm fails to show the inference is deductively invalid; he only shows it doesn\u2019t hold for non-phenomenal uses of &#8220;appears.&#8221;<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. Chisholm\u2019s Shift to Adverbialism<\/strong><\/h3>\n\n\n\n<p>Chisholm later proposes an&nbsp;<strong>adverbial theory<\/strong>&nbsp;(e.g., &#8220;I am appeared to greenly&#8221;) to avoid reifying appearances. Chrucky notes this is a separate debate but hints that Chisholm\u2019s later work (e.g., his 1997 autobiography)&nbsp;<strong>abandons adverbialism<\/strong>, endorsing appearances as &#8220;individual things.&#8221;<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5. Key Implications<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The sense-datum inference&nbsp;<strong>stands<\/strong>&nbsp;for phenomenal appearances, undermining Chisholm\u2019s early critique.<\/li>\n\n\n\n<li>The debate hinges on&nbsp;<strong>distinguishing uses of &#8220;appears&#8221;<\/strong>&nbsp;and whether phenomenal properties are irreducible.<\/li>\n\n\n\n<li>Chisholm\u2019s later reversal suggests the adverbial theory may not fully escape ontological commitments.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Conclusion<\/strong><\/h3>\n\n\n\n<p>Chrucky\u2019s paper clarifies the sense-datum debate by disentangling linguistic ambiguities and defending the inference\u2019s validity in its strongest form. It also highlights shifts in Chisholm\u2019s views, leaving open questions about the metaphysics of perception.<\/p>\n\n\n\n<p><strong>Strengths<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Clear taxonomy of &#8220;appears&#8221; uses.<\/li>\n\n\n\n<li>Effective defense of the phenomenal\/sense-datum link.<\/li>\n\n\n\n<li>Notes Chisholm\u2019s evolving stance.<\/li>\n<\/ul>\n\n\n\n<p><strong>Limitations<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Doesn\u2019t fully engage with Chisholm\u2019s later rejection of adverbialism.<\/li>\n\n\n\n<li>Could explore alternative non-sense-datum accounts of phenomenality.<\/li>\n<\/ul>\n\n\n\n<p>This paper remains relevant for discussions on perception, foundationalism, and the ontology of appearances.<\/p>\n\n\n\n<p>evaluate<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Evaluation of Chrucky\u2019s&nbsp;<em>The Alleged Fallacy of the Sense-Datum Inference<\/em><\/strong><\/h3>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>1. Strengths<\/strong><\/h4>\n\n\n\n<p><strong>(a) Clear Distinction of &#8220;Appears&#8221; Uses<\/strong><br>Chrucky\u2019s taxonomy of&nbsp;<strong>epistemic, comparative, ostensible, and phenomenal<\/strong>&nbsp;uses of &#8220;appears&#8221; is a strong contribution. By showing that Chisholm\u2019s counterexamples mostly rely on&nbsp;<strong>non-phenomenal<\/strong>&nbsp;cases (e.g., &#8220;The woods sound inhabited&#8221;), he successfully isolates the&nbsp;<strong>phenomenal<\/strong>&nbsp;case (&#8220;The curtain appears green&#8221;) as the relevant one for sense-data.<\/p>\n\n\n\n<p><strong>(b) Defense of Phenomenal Appearances<\/strong><br>His argument that&nbsp;<strong>phenomenal appearances<\/strong>&nbsp;(e.g., color, shape) are irreducible counters reductionist attempts (e.g., Bennett, Armstrong). This aligns with foundationalist views that sense-data are necessary for explaining perception.<\/p>\n\n\n\n<p><strong>(c) Exposing Chisholm\u2019s Shifting Position<\/strong><br>Chrucky notes Chisholm\u2019s later abandonment of the&nbsp;<strong>adverbial theory<\/strong>&nbsp;(in favor of treating appearances as &#8220;individual things&#8221;), which undermines Chisholm\u2019s earlier objections to reification. This historical observation strengthens his critique.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>2. Weaknesses<\/strong><\/h4>\n\n\n\n<p><strong>(a) Limited Engagement with Alternative Theories<\/strong><br>Chrucky focuses on defending the sense-datum inference but does not thoroughly engage with&nbsp;<strong>competing theories<\/strong>&nbsp;(e.g., direct realism, intentionalism) that might explain phenomenal appearances without sense-data.<\/p>\n\n\n\n<p><strong>(b) Assumption of Irreducibility<\/strong><br>While he rejects epistemic\/comparative reductions, he does not fully address&nbsp;<strong>contemporary representationalist or enactivist<\/strong>&nbsp;accounts that might dissolve the need for sense-data.<\/p>\n\n\n\n<p><strong>(c) Overemphasis on Deductive Validity<\/strong><br>Chrucky narrowly focuses on whether the inference is deductively valid, but Chisholm\u2019s broader objection\u2014that sense-data are&nbsp;<strong>metaphysically problematic<\/strong>\u2014is not fully countered. Even if the inference is valid, it doesn\u2019t prove sense-data are the best explanation.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>3. Philosophical Significance<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>For Foundationalism<\/strong>: If the sense-datum inference holds, foundationalists retain a basis for empirical knowledge.<\/li>\n\n\n\n<li><strong>For Philosophy of Perception<\/strong>: The paper reinforces the need to distinguish&nbsp;<strong>phenomenal<\/strong>&nbsp;from other uses of &#8220;appears.&#8221;<\/li>\n\n\n\n<li><strong>For Chisholm Scholarship<\/strong>: It highlights an inconsistency in Chisholm\u2019s views, showing his later work may concede the very entities he earlier rejected.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>4. Conclusion<\/strong><\/h4>\n\n\n\n<p>Chrucky\u2019s paper is a&nbsp;<strong>strong defense<\/strong>&nbsp;of the sense-datum inference against Chisholm\u2019s objections, particularly by clarifying the&nbsp;<strong>phenomenal\/non-phenomenal distinction<\/strong>.
