130 years of Earth surface temperatures
Ernst Haeckel and Ernst Mach
Let us now examine the attitude of Machism, as a philosophical current, towards the natural sciences. All Machism, from beginning to end, combats the “metaphysics” of the natural sciences, this being the name they give to natural-scientific materialism, i.e., to the instinctive, unwitting, unformed, philosophically unconscious conviction shared by the overwhelming majority of scientists regarding the objective reality of the external world reflected by our consciousness. And our Machists deceitfully keep silent about this fact and obscure or confuse the inseparable connection between the instinctive materialism of the natural scientists and philosophical materialism as a trend, a trend known long ago and hundreds of times affirmed by Marx and Engels.
