now_o simple_a motion_n can_v proceed_v only_o from_o a_o simple_a body_n that_o be_v from_o a_o body_n which_o move_v by_o its_o own_o power_n therefore_o the_o heaven_n be_v a_o simple_a body_n

the_o first_o and_o most_o perfect_a of_o simple_a body_n but_o the_o circular_a motion_n be_v the_o first_o and_o most_o perfect_a of_o all_o simple_a motion_n because_o all_o circular_a line_n be_v

no_o 〈◊〉_d 〈◊〉_d 〈◊〉_d 〈◊〉_d 〈◊〉_d and_o 〈◊〉_d 〈◊〉_d 〈◊〉_d 〈◊〉_d 〈◊〉_d make_v the_o same_o equivocation_n as_o finish_v and_o end_n this_o philosopher_n prove_v thus_o that_o a_o infinite_a line_n

of_o all_o motion_n therefore_o body_n which_o more_o circular_o be_v simple_a and_o the_o first_o and_o most_o divine_a of_o simple_a body_n his_o four_o argument_n all_o motion_n be_v either_o

the_o four_o element_n there_o must_v be_v then_o a_o simple_a body_n to_o which_o this_o motion_n be_v natural_a therefore_o the_o heaven_n which_o be_v move_v circular_o be_v a_o simple_a body_n differ_v from_o the_o four_o element_n in_o fine_a the_o circular_a motion_n be_v natural_a or_o violent_a in_o some_o body_n if_o it_o be_v natural_a it_o be_v evident_a that_o body_n must_v be_v the_o most_o simple_a and_o perfect_a if_o it_o be_v not_o natural_a it_o be_v very_o strange_a that_o this_o motion_n shall_v continue_v always_o since_o we_o see_v all_o unnatural_a motion_n
