大學之道:在明明德,在親民,在止於至善。知止而后有定,定而后能靜,靜而后能安,安而后能慮,慮而后能得。物有本末,事有終始,知所先後,則近道矣。

古之欲明明德於天下者,先治其國;欲治其國者,先齊其家;欲齊其家者,先脩其身;欲脩其身者,先正其心;欲正其心者,先誠其意;欲誠其意者,先致其知;致知在格物。物格而后知至,知至而后意誠,意誠而后心正,心正而后身脩,身脩而后家齊,家齊而后國治,國治而后天下平。

自天子以至於庶人,壹是皆以脩身為本。其本亂而末治者否矣;其所厚者薄,而其所薄者厚,未之有也。

The following is a possible translation for the beginning:

大學之道在明明德,在親民,在止於至善

The way (道) of the grand study (大學) is to make clear (明) the obvious virtue (明德); to renovate (親) the people (民); and to aim at(止於) the perfection (至善).
