The concept of Malthus, derived from Thomas Robert Malthus’s 1798 essay on population growth, argues that populations grow exponentially while resources expand linearly, resulting in unavoidable shortages. Writers like William Hazlitt pointed out inconsistencies in Malthus’s ideas, emphasizing his shifting stance between rationality and excess, while Leo Tolstoy criticized the theory’s exploitation as a "scientific" rationale for societal inertia.
Samuel McChord Crothers depicted Malthus as a detached, pragmatic individual, and Thomas De Quincey observed his intellectual uncertainty. Leslie Stephen placed discussions about Malthus’s compatibility with divine law or natural selection within a broader context. These differing viewpoints underscore a theme intertwined with morality, economics, and the conflict between human advancement and environmental boundaries.
