Syed Muhammad Naquib Al-Attas said this quote

To know how to put what knowledge in which place is wisdom (hikmah). Otherwise, knowledge without order and seeking it without discipline does lead to confusion and hence to injustice to one's self.

~ Syed Muhammad Naquib Al-Attas

It is like the thirsty traveller who at first sincerely sought the water of knowledge, but who later, having found it plain perhaps, proceeded to temper his cup with the salt of doubt so that his thirst now becomes insatiable though he drinks incessantly, and that in thus drinking the water that cannot slake his thirst, he has forgotten the original and true purpose for which the water was sought.

~ Syed Muhammad Naquib Al-Attas

The greatest challenge that has surreptitiously arisen in our age is the challenge of knowledge, indeed, not as against ignorance; but knowledge as conceived and disseminated throughout the world by Western civilization; knowledge whose nature has become problematic because it has lost its true purpose due to being unjustly conceived, and has thus brought about chaos in man's life instead of, and rather than, peace and justice; knowledge which pretends to be real but which is productive of confusion and scepticism, which has elevated doubt and conjecture to the 'scientific' rank in methodology; knowledge which has, for the first time in history, brought chaos to the Three Kingdom of Nature; the animal, vegetal and mineral.

~ Syed Muhammad Naquib Al-Attas

Justice and injustice indeed begins and ends with the self.

~ Syed Muhammad Naquib Al-Attas
