Enlightenment and The Industrial Revolution, an intimate relationship:

Enligthenment thinkers did not agree on much, e.g, whether the franchise ['voting'] should be open to all or only to a limited group [el.coll; us sen; 3/5s Comp], but did did agree on the idea that Liberty was not possible without the guarantee of property [life, liberty property]. To the intellectuals of the Enligthenment and beyond, these two notions were bound together. John Locke argues:

And reviewing the historical context one can understand why. Given that property in the Old Order was in the hands of 'princes and potentates' and of the 'established church', liberty without property was perceived to be an oxymoron [logically impossible; without property one could not act politically]. It should not surprise then that property was considered a requirement for exercising the franchise / voting. Only those with property could be counted on to defend the state.

Many economists today perceive that:personal freedom, prosperity and private property are closely linked. They observe that:

But all is not so simple: ideals and reality are often in conflict.

The great dilemma of the Enlightenment, and one that we share today may not be the values and aspirations themselves, but understanding what we actually do in their name.
