It may not be an exaggeration to say that everything we have in our modern political and economic system is due to the Scientific Revolution.
From the foundation laid by great thinkers like Francis Bacon, Galileo Galilei, and Isaac Newton, we built the entire edifice of scientific knowledge. With the advent of empirical science, for the first time in human history we had a precise, reliable means of obtaining knowledge about the universe. There had been some advances in knowledge and technology before that point, but they took hundreds of years and were basically trial-and-error. The Scientific Method was a turning point, where human knowledge went from virtual stagnation to an exponential rate of growth.
The change was slow, even imperceptible at the time; but it is almost impossible to overstate the importance of this fundamental shift in human existence. Before science, we were little more than the savannah apes we had evolved from; after science, we are building robots that land on other planets.
All the sciences we now know were built from this foundation: Physics, chemistry, biology, and ultimately psychology, neuroscience, and even economics. The Scientific Revolution brought us industrial technology, then fossil fuel power, then electricity, and ultimately nuclear power, computers, and the Internet. All of this is an outgrowth of that basic Scientific Method first expounded by Francis Bacon.
With industrial technology and a more rational understanding of the universe came also new ways of political thought, and I do not believe it is an accident that modern democracy with universal suffrage and free-market capitalism both emerged in the 18th century, once the Scientific Revolution was in full swing. The concept of an industrial capitalist economy did not exist before that, and in ancient times Greece and Rome had "democracies" that were actually aristocracies. Industrialization brought the first sustained economic growth, the first true democracies, an end to slavery, and ultimately led to the high-tech information services economy we know today. Without the Scientific Revolution we would still live like Medieval serfs.
