He dieth not who giveth life to learning. Whoso honoreth the learned, honoreth me. The worst of men is a bad learned man, and a good learned man is the best. Causes will be submitted to their decision, they will pass sentence without knowledge, will err themselves, and lead others into error. An hour's contemplation is better than a year's adoration.
Philosophy is the stray camel of the Faithful, take hold of it wherever ye come across it.
Go in quest of knowledge even into China. Seek knowledge from the cradle to the grave. The knowledge from which no benefit is derived is like a treasure from which no charity is bestowed in the way of the Lord. The errors of the learned destroy it, the disputations of the hypocrite, and the orders of kings who have lost the road. It is better to teach knowledge one hour in the night than to pray all night.
