But he confined free conscious life activities in subjective scope, and regarded the apriori principles of the activities as the subjective principles of our reflective judgement; thus through the aesthetic activities of free game and the cognition activities of the internal purposiveness of nature, he still thought the transition from theory cognition to moral practice as some kind of symbol, some kind of hint or some kind of mystery.

但是，由于他仍然把人的自由自觉的生命活动局限于主观领域，把源于这一活动的先天原则仍然看作是我们反思性判断力所拥有的主观准则，所以他通过自由游戏的审美活动和自然内在合目的性的认识活动，从人的理论认识向人的道德实践的过渡仍然只是某种象征、暗示或类比，是某种说不出来的神秘的东西。

The improvements were renumbering the frequent 1 item in the support degree descending order and utilizing the Apriori property to prune the redundant extended items which were used to generate the candidate frequent itemsets.
