that_o perhaps_o as_o strong_a as_o any_o we_o shall_v meet_v with_o in_o philosophy_n we_o be_v apt_a to_o think_v that_o the_o cause_n of_o the_o suspension_n of_o the_o mercury_n in_o the_o

for_o we_o can_v only_o conclude_v from_o hence_o that_o the_o equipoise_n of_o liquor_n be_v the_o cause_n of_o the_o mercury_n suspension_n but_o what_o be_v the_o cause_n of_o this_o equipoise_n of_o liquor_n or_o the_o cause_n of_o the_o gravitation_n of_o any_o liquor_n or_o any_o body_n that_o be_v what_o be_v the_o cause_n of_o gravity_n in_o general_n be_v clear_o unknown_a to_o we_o

at_o the_o knowledge_n of_o one_o link_n more_o in_o the_o chain_n of_o natural_a cause_n but_o this_o be_v not_o conclusive_a this_o put_v not_o a_o end_n to_o the_o enquiry_n for_o so_o if_o one_o look_v at_o a_o pendulum_n clock_n shall_v inquire_v why_o the_o pendulum_n do_v not_o cease_v by_o degree_n from_o vibrate_v and_o he_o be_v answer_v that_o it_o be_v keep_v in_o motion_n by_o the_o

he_o have_v mistake_v one_o single_a link_n for_o the_o whole_a chain_n for_o if_o he_o proceed_v far_o and_o have_v inquire_v what_o move_v this_o wheel_n he_o will_v find_v the_o next_o wheel_n and_o so_o onward_o to_o the_o weight_n or_o spring_n but_o here_o he_o be_v at_o a_o loss_n for_o what_o move_v they_o be_v absolute_o unknown_a as_o to_o most_o other_o reason_n in_o natural_a philosophy_n that_o usual_o pass_v as_o satisfactory_a and_o be_v receive_v as_o account_n of_o nature_n proceed_n we_o shall_v general_o find_v they_o little_o more_o than_o far_a illustration_n of_o
