"Science, in content, form, and purpose, is fundamentally social, collective. It is invariably, in its every branch, the sum of knowledge attained by many different people, by past generations and by contemporaries. It is the composite product of collective labours. The facts and conclusions which it comprises are expressed in the form of concepts, definitions, and formulae; they are recorded in writing or in print. The purpose of all this is to facilitate the communication of knowledge to other people, to one's class, one's state, to humanity as a whole. Finally, and this is most important, science is a powerful instrument helping to disclose new productive forces in nature and new means of production. It gives man the means of struggle and of defence. Therefore, science comes into being and develops simultaneously with the rise and development of society, as an inevitable consequence and at the same time an indispensable condition for this development."
- S.I. Vavilov, 1948
