Common law has a culture of judicial inventiveness and even flexibility. Enunciation of principle is not forever paramount but indeed a continuing flow of cases and statutes add to the ebb and flow of the law, whereby 'case law represented the modern man's realisation of his own limitations.' Further differences include where a civilian lawyer speaks in terms of the law of nature while the common lawyer speaks to reason. It follows that the culture of these legal systems has been moulded by perceptions of justice and the means available to attain it.
