can_v strike_v it_o but_o it_o be_v evident_a say_v you_o out_o of_o these_o pretend_a cause_n of_o this_o motion_n that_o such_o atom_n can_v move_v so_o swift_o downward_o as_o a_o great_a dense_a

as_o it_o do_v in_o the_o heat_n of_o the_o day_n the_o same_o may_v be_v say_v of_o summer_n and_o winter_n for_o in_o winter_n time_n the_o atom_n seem_v to_o be_v more_o gross_a and_o consequent_o to_o strike_v more_o strong_o upon_o the_o body_n they_o meet_v with_o in_o their_o way_n as_o they_o descend_v yet_o on_o the_o other_o side_n they_o seem_v in_o the_o summer_n to_o be_v more_o numerous_a as_o also_o to_o descend_v from_o a_o great_a height_n both_o which_o circumstance_n will_v be_v cause_n of_o a_o strong_a stroke_n and_o more_o vigorous_a impulse_n on_o the_o body_n they_o hit_v and_o the_o like_a may_v be_v object_v of_o divers_a part_n of_o the_o world_n for_o in_o the_o torrid_a zone_n it_o will_v always_o happen_v as_o in_o summer_n in_o place_n of_o the_o

depend_v upon_o so_o mutable_a a_o cause_n and_o it_o make_v to_o the_o same_o effect_n that_o a_o body_n which_o lie_v under_o a_o thick_a rock_n or_o any_o other_o very_o dense_a body_n that_o can_v

which_o the_o stroke_n of_o the_o atom_n give_v to_o a_o dense_a body_n be_v a_o determination_n of_o the_o way_n which_o a_o dense_a body_n be_v to_o cut_v to_o itself_o therefore_o multiplication_n

thereby_o determine_v it_o to_o weigh_v to_o the_o centreward_n and_o not_o rise_v float_v upward_o which_o be_v all_o the_o sensible_a effect_n we_o can_v perceive_v next_o we_o may_v observe_v that_o the_o first_o particular_n of_o the_o objection_n do_v not_o reach_v home_o to_o enfeeble_v our_o doctrine_n in_o this_o particular_a although_o we_o admit_v they_o to_o be_v in_o such_o sort_n as_o they_o be_v propose_v for_o they_o withal_o imply_v such_o a_o perpetual_a variation_n of_o cause_n ever_o favourable_a to_o our_o position_n that_o nothing_o can_v be_v infer_v out_o of_o they_o to_o repugn_v against_o it_o as_o thus_o when_o there_o be_v many_o atom_n descend_v in_o the_o air_n the_o same_o general_a cause_n which_o make_v they_o be_v many_o make_v they_o also_o be_v light_n

of_o circumstance_n as_o to_o be_v able_a to_o determine_v when_o there_o be_v absolute_o more_o cause_n of_o weight_n and_o when_o less_o and_o as_o we_o find_v not_o weight_n enough_o in_o either_o

than_o day_n his_o position_n be_v that_o more_o or_o less_o gravity_n contribute_v nothing_o at_o all_o to_o the_o fast_o or_o slow_o descend_v of_o a_o natural_a body_n but_o that_o all_o the_o

it_o go_v fast_o and_o the_o like_a but_o his_o argument_n whereby_o he_o endeavour_v to_o prove_v his_o position_n be_v yet_o more_o wonderful_a for_o find_v in_o pendant_n unequal_a in_o gravity_n that_o the_o light_a go_v in_o the_o same_o time_n almost_o as_o fast_o as_o the_o heavy_a he_o gather_v from_o thence_o that_o the_o different_a weight_n have_v each_o of_o they_o the_o same_o

first_o we_o must_v ask_v he_o whether_o experience_n or_o reason_n teach_v he_o that_o the_o slow_a go_v of_o the_o light_a pendant_n proceed_v only_o from_o the_o medium_fw-la and_o not_o from_o want_n of_o gravity_n and_o when_o he_o shall_v have_v answer_v as_o he_o needs_o must_v that_o experience_n do_v not_o show_v this_o then_o we_o must_v importune_v he_o for_o a_o good_a reason_n but_o i_o do_v not_o find_v that_o he_o bring_v any_o at_o all_o again_o if_o he_o admit_v which_o he_o do_v in_o express_a term_n that_o a_o light_a body_n can_v resist_v the_o medium_fw-la so_o much_o as_o a_o heavy_a body_n can_v we_o must_v ask_v he_o whether_o it_o be_v not_o the_o weight_n that_o make_v the_o heavy_a body_n resist_v more_o which_o when_o he_o have_v acknowledge_v that_o it_o be_v he_o have_v therein_o likewise_o acknowledge_v that_o whenever_o this_o happen_v in_o the_o descend_v of_o a_o body_n the_o more_o weight_n must_v make_v the_o heavy_a body_n descend_v fast_o but_o we_o can_v pass_v this_o matter_n without_o note_v how_o himself_o make_v good_a those_o argument_n of_o aristotle_n which_o he_o seem_v by_o no_o mean_n to_o esteem_v of_o for_o since_o the_o gravity_n overcome_v the_o resistance_n of_o the_o medium_fw-la in_o same_o some_o proportion_n it_o follow_v that_o the_o proportion_n between_o the_o gravity_n and_o the_o medium_n may_v be_v multiply_v without_o end_n so_o as_o if_o he_o suppose_v that_o the_o gravity_n of_o a_o body_n make_v it_o go_v at_o a_o certain_a rate_n in_o imaginary_a space_n which_o be_v his_o manner_n of_o put_v the_o force_n of_o gravity_n then_o there_o may_v be_v give_v such_o a_o proportion_n of_o a_o heavy_a body_n to_o the_o medium_n as_o it_o shall_v go_v in_o such_o a_o medium_n at_o the_o

imaginary_a space_n compare_v to_o that_o other_o body_n which_o he_o suppose_v to_o be_v move_v in_o it_o at_o the_o same_o rate_n which_o no_o man_n will_v stick_v at_o confession_n to_o be_v very_o absurd_a then_o turn_v the_o scale_n because_o the_o resistance_n of_o the_o medium_n somewhat_o hinder_v gravity_n and_o that_o with_o less_o resistance_n the_o heavy_a body_n move_v fast_o it_o must_v follow_v that_o since_o there_o be_v no_o proportion_n betwixt_o the_o medium_n and_o imaginary_a space_n there_o must_v neither_o be_v any_o proportion_n betwixt_o the_o time_n in_o which_o a_o heavy_a body_n shall_v pass_v through_o a_o certain_a quantity_n of_o the_o medium_n and_o the_o time_n in_o which_o it_o shall_v pass_v through_o as_o much_o imaginary_a space_n wherefore_o it_o must_v pass_v over_o so_o much_o imaginary_a space_n in_o a_o instant_n which_o be_v the_o argument_n that_o aristotle_n be_v so_o much_o laugh_v at_o for_o press_v and_o in_o a_o word_n nothing_o be_v more_o evident_a then_o that_o for_o this_o effect_n which_o galileo_n attribute_n to_o gravity_n it_o be_v unreasonable_a to_o put_v a_o divisible_a quantity_n since_o the_o effect_n be_v

every_o power_n shall_v be_v fit_v to_o the_o effect_n or_o end_n for_o which_o it_o be_v put_v another_o argument_n of_o galileo_n be_v as_o bad_a as_o this_o when_o he_o endeavour_v to_o prove_v that_o all_o body_n go_v of_o a_o like_a velocity_n because_o it_o happen_v that_o a_o light_a body_n in_o some_o case_n go_v fast_a than_o a_o heavy_a body_n in_o another_o case_n as_o for_o example_n in_o two_o pendant_n whereof_o the_o light_a be_v in_o the_o begin_n of_o its_o motion_n and_o the_o heavy_a towards_o the_o end_n of_o it_o or_o if_o the_o light_a hang_v at_o a_o long_a

light_a go_v fast_o than_o a_o heavy_a because_o a_o great_a force_n can_v make_v it_o go_v fast_o for_o it_o be_v manifest_a that_o in_o a_o violent_a motion_n the_o force_n which_o move_v a_o body_n

with_o they_o their_o way_n see_v then_o that_o such_o a_o gentle_a motion_n of_o the_o air_n be_v able_a to_o put_v a_o feather_n out_o of_o its_o way_n notwithstanding_o the_o percussion_n of_o the_o atom_n upon_o it_o why_o shall_v it_o not_o likewise_o put_v a_o piece_n of_o iron_n out_o of_o its_o way_n downward_o since_o the_o iron_n have_v nothing_o from_o the_o atom_n but_o a_o

the_o water_n will_v run_v out_o at_o that_o hole_n to_o obey_v its_o more_o powerful_a impulse_n to_o the_o centreward_n rather_o than_o continue_v the_o violent_a motion_n in_o which_o it_o have_v arrive_v to_o a_o great_a degree_n of_o celerity_n which_o be_v so_o it_o be_v easy_a to_o conceive_v that_o the_o atom_n in_o the_o wind_n or_o water_n which_o move_v perpendicular_o downward_o will_v still_o continue_v the_o iron_n motion_n downward_o notwithstanding_o the_o medium_n slope_v motion_n since_o the_o prevail_a force_n determine_v both_o the_o iron_n and_o the_o medium_fw-la

when_o it_o be_v sink_v in_o a_o current_n of_o wind_n or_o water_n you_o must_v remember_v that_o the_o dense_a body_n itself_o have_v a_o particular_a virtue_n of_o its_o own_o namely_o its_o

may_v be_v conceive_v to_o be_v more_o or_o less_o impartible_a than_o it_o be_v active_a or_o heavy_a a_o for_o example_n let_v we_o of_o a_o dense_a element_n take_v any_o one_o lest_o part_n

little_a by_o reason_n of_o the_o littleness_n of_o its_o quantity_n so_o that_o thus_o you_o see_v a_o extremity_n of_o the_o effect_n of_o density_n join_v together_o in_o one_o body_n by_o the_o accident_n of_o its_o littleness_n with_o a_o contrary_a extremity_n of_o the_o effect_n of_o gravity_n or_o rather_o with_o the_o want_n of_o it_o each_o of_o they_o within_o the_o limit_n of_o the_o

general_a course_n of_o natural_a cause_n to_o be_v more_o divisible_a then_o to_o be_v a_o divider_n though_o according_a to_o the_o nature_n of_o the_o degree_n consider_v absolute_o in_o
