However, several philosophical counterarguments challenge this claim:<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">1. <mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-purple-color\">Radical Skepticism (Evil Demon Hypothesis)<\/mark><\/h3>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Descartes himself introduces the possibility of an omnipotent evil demon systematically deceiving us.

For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The demon could make us &#8220;see&#8221; a square as having 5 sides in a dream, or convince us that 2 + 3 = 6.<\/li>\n\n\n\n<li>Even innate ideas (like math) could be implanted deceptively, rendering them unreliable.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">2. <mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-purple-color\">Non-Euclidean Geometry and Alternative Mathematical Systems<\/mark><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Modern mathematics shows that truths like &#8220;a square has four sides&#8221; or &#8220;2+3=5&#8221; depend on <strong>axiomatic systems<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In non-Euclidean geometries, shapes can defy Euclidean properties (e.g., a &#8220;square&#8221; on a curved surface may not have four equal sides or right angles).<\/li>\n\n\n\n<li>In modular arithmetic (e.g., modulo 4), 2 + 3 = 1, not 5.<br>If a dream operates under non-standard axioms, these &#8220;certainties&#8221; could be false within that framework.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">3. <mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-purple-color\">Cognitive Fallibility in Altered States<\/mark><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Dreams often involve distorted logic and impossible scenarios:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>We might dream of a &#8220;square&#8221; with 5 sides and accept it as normal, or perceive 2 + 3 = 5 as false.<\/li>\n\n\n\n<li>Neurobiological studies show dreaming can impair rational cognition, making even basic logic unreliable.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">4. <mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-purple-color\">Conceptual Relativity<\/mark><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The meaning of &#8220;square&#8221; or &#8220;addition&#8221; depends on linguistic and conceptual frameworks:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If a dream redefines these concepts (e.g., &#8220;square&#8221; means a five-sided shape), the truths dissolve.<\/li>\n\n\n\n<li>This aligns with Wittgenstein\u2019s view: mathematical truths are rules of language, not immutable realities.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">5. <mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-purple-color\">Empiricist Critique<\/mark><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Hume and later empiricists argue that all knowledge (including math) derives from sensory experience.
