Accordingly, Since Nothing Prevents The Earth From Moving, I Suggest That We Should Now Consider Also Whether Several Motions Suit It, So That It Can Be Regarded As One Of The Planets. For, It Is Not The Center Of All The Revolutions.

So Far As Hypotheses Are Concerned, Let No One Expect Anything Certain From Astronomy, Which Cannot Furnish It, Lest He Accept As The Truth Ideas Conceived For Another Purpose, And Depart From This Study A Greater Fool Than When He Entered It.

Among The Authorities It Is Generally Agreed That The Earth Is At Rest In The Middle Of The Universe, And They Regard It As Inconceivable And Even Ridiculous To Hold The Opposite Opinion. However, If We Consider It More Closely The Question Will Be Seen To Be Still Unsettled, And So Decidedly Not To Be Despised. For Every Apparent Change In Respect Of Position Is Due To Motion Of The Object Observed, Or Of The Observer, Or Indeed To An Unequal Change Of Both.
