心理学告诉我们,思维过程是从问题开始,问题的起点是“疑”。疑,乃学之端,思之始,容易引起定向反映———探究反映。有了这种反映,就会积极思维,努力探求,进而获得真知。思维从问题开始,并在解决问题的过程中得到发展。宋代学者朱熹说过:“读书无疑者须教有疑,有疑者却要无疑, Psychology tells us that the process of thinking starts from the problem and the starting point of the problem is “suspect.” Suspicion is the end of learning, the beginning of thinking, it is easy to cause directional reflection --- inquiry reflection. With this kind of reflection, we will actively think, strive to seek, and gain knowledge. Thinking starts with the problem and develops in the process of solving the problem. Scholar Song Zhu of the Song Dynasty said: “Undoubtedly the reader must be skeptical, but the suspicious person must have no doubt.
