“Marx, Engels, and Lenin have carried on the tradition of rational and non-mystical approach to all human problems; this is the tradition of the best Greek philosophers and the founders of modern science. Careful analysis; separation of factors; the following of causes into their effects; reliance on experiments; all are taken over into Marxism and provide it with a hard scientific core. There is nowhere any pandering to special intuitions or spiritual experiences.” ScienceMarxismEngelsLeninDialectical Materialism Book:Engels and Science Source: Engels and Science
“Every chemical compound, according to Engels, comes into existence only at a certain time in the development of the universe when the conditions are appropriate for it; and when it does come into existence it manifests this by entering into its characteristic relations. Neither carbon compounds or proteins are ideal forms, but are themselves witnesses of the conditions on a cooling planet. It is here that occurs his celebrated remark that life is the mode of existence of proteins.” CommunismBiologyMarxismMarxBiochemistryEngelsDialectical Materialism Book:Marx and science Source: Marx and science
