Montesquieu

As men are made to pre­serve, feed, and clo­the them­sel­ves, and do eve­ry­thing a society requi­res, reli­gion should not give them too contem­pla­tive a life.1

The Mohammedans become spe­cu­la­tive by habit : they pray five times a day, and each time they must per­form an act by which they cast eve­ry­thing that belongs to this world behind them : that pre­pa­res them for spe­cu­la­tion. Add to this their indif­fe­rence for all things which the doc­trine of inal­te­ra­ble fate confers.

If some other cau­ses concur to ins­pire their detach­ment, as if the har­sh­ness of the govern­ment, if the laws bea­ring on owner­ship of the land, ins­till a pre­ca­rious spi­rit, all is lost.

The reli­gion of the Gaurs once made the king­dom of Persia flou­rish ; it cor­rec­ted the ill effects of des­po­tism ; the Mohammedan reli­gion today is des­troying that very empire.

That is the disadvantage of the doctrine of Foe and Laockium.
