Divide and rule, the politician cries; Unite and lead, is watchword of the wise. - Johann Wolfgang von Goethe

However often we turn to it [the Qur'an] at first disgusting us each time afresh, it soon attracts, astounds, and in the end enforces our reverence... Its style, in accordance with its contents and aim is stern, grand, terrible — ever and anon truly sublime — Thus this book will go on exercising through all ages a most potent influence.

Not to keep from error, is the duty of the educator of men, but to guide the erring one, even to let him swill his error out of full cups — that is the wisdom of teachers. Whoever merely tastes of his error, will keep house with it for a long time, ... but whoever drains it completely will have to get to know it.

Life belongs to the living, and he who lives must be prepared for changes.
