INFP哲学家型-富有创造力的探索者，喜欢随性生活的人生(22)

最后，对INFP来说，Si功能一个最重要的作用是帮助他们唤醒并整合他们过去的人生经验和教训，从而使INFP不再重复过去犯过的错误，帮助他们辨明他们未来的道路。过去的这些探索经验和结论也会逐步形成INFP对自我认知的信心，帮他们建立起更稳固的自我的概念。
INFPs’ Inferior Function: Extraverted Thinking (Te)

INFP的第四功能：外向思考（Te）

Whether they realize it or not, INFPs’ life quest is well understood as one of discovering and integrating their inferior function, which is sometimes called the “lost” or “missing” function. There is something indelibly magical and mysterious about the inferior function, which makes it a powerful source of energy and motivation for all types.
无论他们是否意识得到，INFP的人生诉求在他们发现并整合了他们的第四功能（Te外向思考）后将变得很好理解，然而可惜的是，Te功能几乎是他们一个遗失掉的功能。
Te功能有着几乎魔术般的神奇力量，使得它几乎成为所有人格型的重要能量和动力来源。
INFPs’ inferior function, Extraverted Thinking (Te), approaches and structures the world in explicitly rational ways. It may do so for the sake of acquiring knowledge (e.g., science), developing new tools and technologies, or maintaining order by ways of explicit rules, policies, and procedures. As an extraverted judging function, it also serves as a tool for verbally asserting, in a deliberate and rational fashion, judgments and directives.
