人類進入二十一世紀，為什麼學“易經”的人和需要瞭解“易經”的人越來越多，究其原因主要有五個方面： 1、由於全球環境污染越來越嚴重，人類的生活環境面臨嚴重挑戰，需要從《周易》中尋找天人合一的思想。 2、越是科技發達，物質越豐富，造成的社會問題就越多。如人際關係、婚姻、家庭、單身主義等等，需要從《周易》中尋找答案。 3、隨著生命科學的發展，人們需要瞭解和探討這一領域的新知識。 4、經濟全球一體化，地球變的越來越小，而每個人的前途機遇和選擇卻越來越多，預測前途的願望也越來越強烈，於是通過《周易》掀起了一股預測熱。 5、由於科學的綜合化和整體化需要向《周易》尋找整體思維方式。由此可見捲入《周易》熱潮的人們有的崇拜、有的理智、有的盲目、有的迷信。面對《周易》熱，筆者談談孔子《易》與人學的實用關係。
