1.OntologicalFoundation:Nature,Human,andExistence

Feuerbach’sontologyoverturnstheidealistprimacyof“spirit”or“thought,”anchoringrealityinthematerialityofnatureandtheconcretenessofhumanexistence.

1.1PriorityofNature(*Naturvorrang*)

Natureexistsindependentlyofhumanconsciousness;itisthe“primordial,uncreatedbasis”ofallbeings(includinghumans).

Naturallaws(e.g.,causality,materialinteraction)governboththeexternalworldandhumanbiology,rejectingsupernaturalor“spiritual”originsofreality.

1.2HumanasaNaturalBeing(*DerMenschalsNaturwesen*)

Humansarenot“transcendentalsubjects”(Kant/Hegel)butsensuous,corporealbeingsembeddedinnature:

Thebody(sensuality)isthemediumofperceptionandinteractionwiththeworld.

Mentalphenomena(thought,emotion)arerootedinbiological/physiologicalprocesses,notabstract“spirit.”

2.EpistemologicalTurn:FromSpeculationtoSensoryIntuition

2.1CritiqueofHegelianIdealism

Hegel“inverts”reality:hemakesthought(*Begriff*)thesourceofbeing,reducingnatureandhumanexistenceto“externalizationsoftheIdea.”

Feuerbachretorts:*“Thinkingisapropertyofman,notmanapropertyofthinking”*—thoughtisa*function*ofthehumanorganism,notitsessence.

2.2SensoryIntuitionasEpistemicFoundation

3.LogicofReligiousCriticism:Alienationandthe“HumanEssence”

3.1ReligionasAlienationofHumanEssence

The“essenceofGod”istheprojectedessenceofhumanity:attributeslikeomnipotence,omniscience,andloveareidealizedhumanpotentials(reason,morality,sociality)divorcedfromrealhumansanddeified.

Example:TheChristianGodis*“man’sself-consciousnessraisedtoinfinity”*—humansworshiptheirownspecies-essenceasatranscendent,supernaturalpower.

3.2DeconstructionofChristianity
