The subject matter of research is contradictions and moral-legal antinomies arising in the philosophy of science, in relation to a set of technologies called “Anti-Plagiarism”. The formal-logical and formal-axiological aspects of the notions “property”, “common property”, “private property”, “theft”, “plundering” and others are considered. The paper argues for the urgent necessity to allow authors unlimited reuse of any fragments of their previously published texts in their new publications actually containing novel scientific results. The condition is that such duplication is indispensable for understanding and rechecking the novel discovers. The scientific novelty: theoretic arguments are exemplified by a hitherto never published new scientific result made within a discrete mathematical model of natural law of private and common ownership.
