Liberalism can be summed up as the postulate of the free use by each individual or member of a society of his property (the fact that some have only one property: their workforce while others own the means of production is not denied, only omitted). In this sense, all men are equal, a fact enshrined in the fundamental principle of the bourgeois constitution: all are equal before the law, the concrete basis of formal equality between the members of a society. In an extension of this, a second idea proposes the commonwealth, according to which property and freedom-based social organization serves the good of all. (Incidentally, if there is no antagonism between social classes, action can be driven by reason, hence rationalism.)
