Practice in Ideology for Althusser
Althusser’s work “Ideology and ISAs” strongly hints to me a Marxist concern with movements of physical bodies. This is undoubtedly in line with Marx’s rejection of Hegel and Feuerbach, who for him dwelled too deeply in a world where Ideas occupy a certain privileged territory (such that from them arise physical realities), and also is touched on lightly when Althusser briefly engages with Aristotle, shirking the full potential of his ideas, but conceding that he gives some credence to “matter in its ‘physical’ modality”.
What I read from Althusser here is an assertion of how physical bodies (flesh and bone humans) articulated by social conditions (their daily “jobs” and acts of consumption) have the ability both to be constitutive of Ideology and, in equal turn, constituted by it. We are offered a jocular example by Pascal, who inverts a conception of a religious ritual, writing that one must “Kneel down, move your lips in prayer, and you will believe.”
A broad tradition of philosophical writing would hardly believe that thoughts sprout from actions, as opposed to the other way around. This particular idea, to consider it more loosely, is also one that young children are taught by their parents, who repeat the catechism of “Think before you act”—not that this is bad advice.
But if we buy Pascal, and similarly Althusser, it is hard to deny that habits in physical reality very seriously engender corresponding mental notions; these notions often give symbiotic life back to our habits, providing the comfort of Rationale and Reason for the seemingly sense impulses that guide our bodies through action.
When we engage Marxist vocabulary words of Practice and Ritual, it elucidates the quiet truth that even the most minute things humans do—the handshake is a good example here—can be chased up to reveal certain routines that make up systems whose functioning has become normalized. Some decades ago, where a white American sat on the bus everyday was part of a larger coded system of human relationships that explicitly denoted the subordination of black people. When you are avoiding the empty subway car because you suspect that there is a homeless person within it, you are not merely acting viscerally but also OK’ing (whether this guilt falls on you in full is up to you) the result of decades of racist housing policies. When you cross the street when the light is red, you are displaying an awareness of, how even though you are aware that Law permeates society, how law on the books is not always equivalent to law in the world. When you get a flu shot, you are consenting to the epistemological basis of the farcical Scientific Method and the lie of Medicine (just kidding). By spiking your Mohawk in the morning after getting dressed for school, you exhibit how thin the line is between conformity and deviance. By going to school, you are taking the carrot of meritocratic Education and drilling yourself in punctuality so that, to paraphrase Marx, you return to the office every morning at 9 on the dot.
To think like this is not too far a stone throw away from Marx, for whom the daily toil of human bodies is the point of departure for ascribing a complex world of both social topology and mental states.
The soldier for whom killing is no small issue does not only think that killing for a moral cause is normal. The soldier also goosesteps, loudly enunciates Hoo-rahs. The sonic and kinetic elements of the act are necessary for the Ideology to be concrete. Subjection is not merely “brainwashing”, mental conditioning—it is Theater.
