Common sense is not something rigid and stationary, but is in continuous transformation, becoming enriched with scientific notions and philosophical opinions that have entered into common circulation. 'Common sense' is the folklore of philosophy and always stands midway between folklore proper (folklore as it is normally understood) and the philosophy, science, and economics of the scientists. Common sense creates the folklore of the future, a relatively rigidified phase of popular knowledge in a given time and place.

Is it better to work out consciously and critically one's own conception of the world and thus, in connection with the labours of one's own brain, choose one's sphere of activity, take an active part in the creation of the history of the world, be one's own guide, refusing to accept passively and supinely from outside the moulding of one' own personality?

Telling the truth is always revolutionary

The people themselves are not a homogeneous cultural collectivity but present numerous and variously combined cultural stratifications which, in their pure form, cannot always be identified within specific historical popular collectivities.

History is at once freedom and necessity.
