　　The　faculty　of　knowledge　from　a　priori　principles　may　be　called　pure　reason；　and　the　general　investigation　into　its　possibility　and　bounds　the　Critique　of　Pure　Reason。　This　is　permissible　although　〃pure　reason；〃　as　was　the　case　with　the　same　use　of　terms　in　our　first　work；　is　only　intended　to　denote　reason　in　its　theoretical　employment；　and　although　there　is　no　desire　to　bring　under　review　its　faculty　as　practical　reason　and　its　special　principles　as　such。　That　Critique　is；　then；　an　investigation　addressed　simply　to　our　faculty　of　knowing　things　a　priori。　Hence　it　makes　our　cognitive　faculties　its　sole　concern；　to　the　exclusion　of　the　feeling　of　pleasure　or　displeasure　and　the　faculty　of　desire；　and　among　the　cognitive　faculties　it　confines　its　attention　to　understanding　and　its　a　priori　principles；　to　the　exclusion　of　judgement　and　reason；　（faculties　that　also　belong　to　theoretical　cognition；）　because　it　turns　out　in　the　sequel　that　there　is　no　cognitive　faculty　other　than　understanding　capable　of　affording　constitutive　a　priori　principles　of　knowledge。　Accordingly　the　critique　which　sifts　these　faculties　one　and　all；　so　as　to　try　the　possible　claims　of　each　of　the　other　faculties　to　a　share　in　the　clear　possession　of　knowledge　from　roots　of　its　own；　retains　nothing　but　what　understanding　prescribes　a　priori　as　a　law　for　nature　as　the　complex　of　phenomena…the　form　of　these　being　similarly　furnished　a　priori。　All　other　pure　concepts　it　relegates　to　the　rank　of　ideas；*　which　for　our　faculty　of　theoretical　cognition　are　transcendent；　though　they　are　not　without　their　use　nor　redundant；　but　discharge　certain　functions　as　regulative　principles。**　For　these　concepts　serve　partly　to　restrain　the　officious　pretentions　of　understanding；　which；　presuming　on　its　ability　to　supply　a　priori　the　conditions　of　the　possibility　of　all　things　which　it　is　capable　of　knowing；　behaves　as　if　it　had　thus　determined　these　bounds　as　those　of　the　possibility　of　all　things　generally；　and　partly　also　to　lead　understanding；　in　its　study　of　nature；　according　to　a　principle　of　completeness；　unattainable　as　this　remains　for　it；　and　so　to　promote　the　ultimate　aim　of　all　knowledge。
