Mid-16th century from Latin extrūdere, from ex- (“out”) + trūdere (“to thrust”).

His extrusion seemed to be a punishment for not being rich. — What Will People Say? A Novel, Rupert Hughes
The above extrusion of permanent things affords an example of the maxim which inspires all scientific philosophising, namely "Occam's razor": Entities are not to be multiplied without necessity. In other words, in dealing with any subject-matter, find out what entities are undeniably involved, and state everything in terms of these entities. — Our Knowledge of the External World as a Field for Scientific Method in Philosophy, Bertrand Russell
IX ON THE NOTION OF CAUSE In the following paper I wish, first, to maintain that the word "cause" is so inextricably bound up with misleading associations as to make its complete extrusion from the philosophical vocabulary desirable; secondly, to inquire what principle, if any, is employed in science in place of the supposed "law of causality" which philosophers imagine to be employed; thirdly, to exhibit certain confusions, especially in regard to teleology and determinism, which appear to me to be connected with erroneous notions as to causality. — Mysticism and Logic and Other Essays, Bertrand Russell
