No One Nor Anything Can Silence Me.

There Is Nothing In This World That I Fear To Say.

Elements Which Are Similar As Regards Their Chemical Properties Have Atomic Weights Which Are Either Of Nearly The Same Value (eg. Pt, Ir, Os) Or Which Increase Regularly (eg. K, Ru, Cs).

No One Nor Anything Can Silence Me.

If All The Elements Are Arranged In The Order Of Their Atomic Weights, A Periodic Repetition Of Properties Is Obtained. This Is Expressed By The Law Of Periodicity.

It Is The Function Of Science To Discover The Existence Of A General Reign Of Order In Nature And To Find The Causes Governing This Order. And This Refers In Equal Measure To The Relations Of Man - Social And Political - And To The Entire Universe As A Whole.
