Leon Trotsky said this quote
“ We seek to uncoverbehind the events changes in the collective consciousness. We reject wholesale references to the “spontaneity” of the movement, references which in most casesexplain nothing and teach nobody. Revolutions take place according to certain laws. This does not mean that the masses in action are aware of the laws of revolution, but it does mean that the changes in mass consciousness are not accidental, but are subject to an objective necessity which is capable of theoretic explanation, and thus makes both prophecy and leadership possible. ”
