Only through Science and Technology, Western Civilization came to be the dominant culture of the world. 400 years ago, all cultures were more or less equally dominant.
Not entirely true. 400 (really 500-600) years ago, the Muslim, Chinese, Indian (Mogul) and European civilizations were on an approximately level playing field. This was at a level that had not changed dramatically for thousands of years. Western Civ took off from that point, leaving all others in the dust. As you point out, this was mainly due to technology.
But why did WC develop science when others (notably China), despite a big early lead, did not? Very interesting subject.
