He who finds a new path is a pathfinder, even if the trail has to be found again by others; and he who walks far ahead of his contemporaries is a leader, even though centuries pass before he is recognized as such.

Ibn Khaldun

The past resembles the future more than one drop of water resembles another.

Ibn Khaldun

The term of life of a dynasty does not normally exceed three generations. For in the first generation are still preserved the characteristic features of rough, uncivilized rural life, such as hard conditions of life, courage, ferocity, and partnership in authority.

Therefore the strength of the 'Asabiya is maintained ...

Asabiya (social solidarity)

Ibn Khaldun

“Two truths cannot contradict one another.” 

Ibn Rushd

How can the heart travel to God, when it is chained by its desires?

Ibn Arabi

The ignorant one does not see his ignorance as he basks in its darkness; nor does the knowledgeable one see his own knowledge, for he basks in its light

Ibn Arabi

The body's weakness comes from illnesses, while the heart's weakness comes from sins.

And just as the body does not taste the delights of food when it is ill, the heart does not taste the delights of worship when it is sinful.

Dhul-Nun al-Misri

Ignorance leads to fear, fear leads to hate, and hate leads to violence. This is the equation.

Ibn Rushd

If the soul is impartial in receiving information, it devotes to that information the share of critical investigation the information deserves, and its truth or untruth thus becomes clear. However, if the soul is infected with partisanship for a particular opinion or sect, it accepts without a moment's hesitation the information that is agreeable to it. Prejudice and partisanship obscure the critical faculty and preclude critical investigation. The results is that falsehoods are accepted and transmitted.

Ibn Khaldun
