So does the Bible (not to quote over again the passages which I have already given you from St. Paul, and One greater than St. Paul) declare the permanence of natural laws, and the trustworthiness of natural phenomena as obedient to God. And so does the Church of England. For she has incorporated into her services that magnificent hymn, which our forefathers called the Song of the Three Children; which is, as it were, the very flower and crown of the Old Testament; the summing up of all that is true and eternal in the old Jewish faith; as true for us as for them: as true millions of years hence as it is now--which cries to all heaven and earth, from the skies above our heads to the green herb beneath our feet, "O all ye works of the Lord, bless ye the Lord; praise Him and magnify Him for ever." On that one hymn I take my stand. That is my charter as a student of Natural Science. As long as that is sung in an English church, I have a right to investigate Nature boldly without stint or stay, and to call on all who have the will, to investigate her boldly likewise, and with Socrates of old, to follow the Logos whithersoever it leads. The Logos. I must pause on that word. It meant at first, no doubt, simply speech, argument, reason. In the mind of Socrates it had a deeper meaning, at which he only dimly guessed; which was seen more clearly by Philo and the Alexandrian Jews; which was revealed in all its fulness to the beloved Apostle St. John, till he gathered speech to tell men of a Logos, a Word, who was in the beginning with God, and was God; by whom all things were made, and without Him was not anything made that was made; and how in Him was Life, and the Life was the light of men; and that He was none other than Jesus Christ our Lord. Yes, that is the truth. And to that truth no man can add, and from it no man can take away. And as long as we believe that as long as we believe that in His light alone can we see light--as long as we believe that the light around us, whether physical or spiritual, is given by Him without whom nothing is made--so long we shall not fear to meet Light, so long we shall not fear to investigate Life; for we shall know, however strange or novel, beautiful or awful, the discoveries we make may be, we are only following the Word whithersoever He may lead us; and that He can never lead us amiss I. THE SOIL OF THE FIELD {2} My dear readers, let me, before touching on the special subject of this paper, say a few words on that of the whole series.
