Louis Althusser on the role of philosophy
“In the battle that is philosophy all the techniques of war, including looting and camouflage, are permissible.”
― Louis Althusser, Philosophy and the Spontaneous Philosophy of the Scientists: And Other Essays

“Philosophy is, in the last instance, class struggle in the field of theory.”
― Louis Althusser, Essays in Self-Criticism
“One of the goals of philosophy is wage theoretical battle. That is why we can say that every thesis is always, by its very nature, an antithesis. A thesis is only ever put forward in opposition to another thesis, or in defence of a new one.”
― Louis Althusser, Philosophy of the Encounter: Later Writings, 1978-87
"Without claiming to be exhaustive, I maintain that every philosophy reproduces within itself, in one way or another, the conflict in which it finds itself compromised and caught up in the outside world.”
― Louis Althusser, Philosophy of the Encounter: Later Writings, 1978-87
“Everything that happens in philosophy has, in the last instance, not only political consequences in theory, but also political consequences in politics: in the political class struggle.”
― Louis Althusser, Essays in Self-Criticism
“To philosophize with open eyes is to philosophize in the dark. Only the blind can look straight at the sun.”
--- Louis Althusser
