「法與時轉」，乃勢所必然。憲法的制定有其社會、政治，經濟等各種力量求取平衡的結果，然而國家、社會、政治、經濟等各種力量又不停的消長，為適應此種情勢的需要，原定的憲法就必須不斷地變遷，以求適應。因此憲法既為適應國家社會情勢的產物，而情勢不可能經久不變，由於情勢的轉移，使憲法不得不依不同的方式而改變，以求適應新的社會狀況，新的國家政策，乃至新的思想觀念，以及多元因素交互作用的結果。因此，當現實政治狀況和社會需要發生變動時，作為維持秩序和安定規範與力量的憲法，首需隨此變動而有所因應，這種動態的現象，就是憲法的變遷。 憲法為憲政的規範，憲政則為憲法的實踐。憲法在制定的過程中，必經激烈的爭辯，然後彼此退讓、容忍、折衷，妥協，因此不可能十全十美；一定有其矛盾、衝突、遺漏，殘缺等現象。這種現象必須靠時間的推演，環境的改變，法院的解釋，以及政治家的智慧，不斷地去洗滌，調適與修補，才能使憲政制度更健全，規範的內容更豐碩，其功能更踏實。名憲法學家亨利．梅茵(Sir Henry Maine)曾謂：「憲法生於成長，而非生於製造」。布魯翰(Lard Brougham)教授亦謂：「凡有價值的憲法，皆必然出於生長，先生根繼成熟，然後乃長久生存」。故一般而論，憲法法典是靜態而沒有生命的文字符號；但憲法中的規定，一旦付諸實施，進入動態的憲政狀況之後，就具有了生命，有生命就有成長。 本文僅就憲法和憲政，從靜態的精神面到動態的制度面；從憲法文字上的條例，到憲政制度上的具體措施，進而闡述因應國家現實政治的需要，而經過不斷地變遷，發展和成長。冀能以此作為制憲行憲之參考。

　　　　　It is inevitable that laws transform with different circumstances. The making of a constitution is the outcome of the interaction among social, political, and economic forces, all of which find balance when interacting with one another. However, since the social, political, and economic forces of a country grow and decline relatively and at different times, a constitution must adjust itself to adapt to new situations. A constitution provides norms for a nation's constitutionism, which, in turn, is the practice of a nation's constitution. During the process of making a constitution, there must be intense debates, which are followed by conceding, tolerance, eclecticism, and compromise. Therefore, a constitution is bound to be imperfect, contradictory, conflicting, omissive, and fragmentary. These problems must be modified with a s time goes b y, a s circumstances change, as the court interprets, and as statesmen use their wisdom. In general, constitutional codes are only words and symbols without life, but they will get life and grow when being put into practice. This paper focuses on constitutions and constitutionalism with a view shuttling between the restful spiritual to the dynamic institutional sides. This paper also makes specific suggestions for the making and practicing of a constitution by interpreting constitutional clauses, by analyzing concrete measures of constitutional institutions, and by illustrating that the incessant changing, development, and growth of a constitution are meant to meet a nation's practical needs.
