Man's grandeur is that he knows himself to be miserable.

Just as I do not know where I came from, so I do not know where I am going. All I know is that when I leave this world I shall fall forever into oblivion, or into the hands of an angry God, without knowing which of the two will be my lot for eternity. Such is my state of mind, full of weakness and uncertainty. The only conclusion I can draw from all this is that I must pass my days without a thought of trying to find out what is going to happen to me.

However vast a man's spiritual resources, he is capable of but one great passion.

If a man loves a woman for her beauty, does he love her? No; for the smallpox, which destroys her beauty without killing her, causes his love to cease. And if any one loves me for my judgment or my memory, does he really love me? No; for I can lose these qualities without ceasing to be.

Faith is a gift of God.

Muhammad established a religion by putting his enemies to death; Jesus Christ by commanding his followers to lay down their lives.

Just as all things speak about God to those that know Him, and reveal Him to those that love Him, they also hide Him from all those that neither seek nor know Him.
