The epoch immediately prior to the Holocene was the Pleistocene that stretched back 2.6 mil-
lion years. What distinguished the Pleistocene was that it went through repeated stretches of
glaciations and brief warmings. These fluctuations made for such unstable and generally cold
climatic conditions that nothing approximating settled human life could develop. Human
hunter-gatherers emerged toward the end of the Pleistocene. The Holocene arrived just 11,700
years ago – bringing into being a moderately warm and relatively stable set of climate condi-
tions that enabled the biosphere and its biodiverse ecosystems to develop maximally resilient
forms. This is when human living began to be radically transformed from hunting and gather-
ing, following the weather, vegetation, and the animals, to agriculture, which exploded 8,000
years ago. Agriculture makes possible the emergence of cities and with them all the arts, sci-
ences, and technological innovations that are constitutive of what we think of as human civi-
lization. If this is broadly accurate, then it follows that the rational intelligibility of human
civilization is dependent on, and therefore nondetachable from, Holocene nature – human
civilization is (was) Holocene civilization. Nature, it transpires, is not a permanent, unchang-
ing, background and resource for human social action; living nature is historical. It is that
historicality, dependence, and nondetachability that constitute the naturalism of Critical Nat-
uralism as the necessary self-consciousness of historical humanity having been constituted
through the environmental beneficence and resilience of the Holocene, and then deposited by
capitalism’s ecocidal actions in the Anthropocene. Said otherwise, humans are not essentially
rational animals, linguistic animals, political animals, cooperative animals, souls, autonomous
subjects, or persons; rather, the arrival of the Anthropocene forces us to become aware that the
defining capacities of the human are the means through which human niche constructing prac-
tices (Gregorata, et al. 2022, 140) carry out the requirements for biological reproduction
through historically dynamic social practices. We are innovative niche constructors and engi-
neers.
B.) The Necessity of Critical Self-Reflection. Fossil fuel capitalism, with its twin evils of global
warming as caused by the emitting of CO

into the atmosphere – from 285ppm in 1850 to
320ppm in 1950 to 420.99ppm in June 2022 – and the massive destruction of ecological hab-
itats, are the joint direct causes of the destruction of Holocene nature. But that destruction of
Holocene nature is not a contingent feature of capitalism: as first-generation critical theory and
ecofeminism both argue, the seismic contradiction at the core of capitalism is its structurally
