This book, a portion of which was published in the American Israelite in 1883, is intended to show the efforts that the human mind has made to solve the great problem of the Divine existence.<br><br>It is safe to say - and were it for no other reason but because Atheism can never succeed in proving the impossibility of the existence of God - the attempts to argue the Divine existence will be renewed and continued in every generation, no matter how much there will be said or written against it.<br><br>It has been often maintained that the triumphs of natural sciences in our century have shaken the foundation of all proofs of the Divine existence. That is not so: just the reverse has been accomplished by the scientifically proved idea of the "Unity of Nature."<br><br>This idea, which means that the laws of nature arc all-embracing, that the most distant planets have some of the same kind of minerals that the earth contains, and that heat, light, electricity, magnetism and chemical affinity - this pentarchy of physical force - are so intricately related that they can be converted into one another, implies the ideas of the five main arguments for the existence of God.
