Descartes’s changing mind

Descartes is always concerned about knowledge. However, the Galileo affair in 1633, the reactions to his Discourse on method, and later his need to reply to objections to his Meditations provoked crises in Descartes’s intellectual development the import of which has not been sufficiently recognized. These events are the major reasons why Descartes’s philosophical position concerning how we know and what we may know is radically different at the end of his life from what it was when he began. We call this later position Descartes’s epistemic stance and contrast it with his earlier methodological, metaphysical realism. Yet Descartes’s epistemic views cannot be separated from other aspects of his work, for example, his views concerning God, causality, metaphysics, and the nature of science. A further meta-implication is that serious errors await any scholar who cites early Cartesian texts in support of late Cartesian positions, or who uses later texts in conjunction with early ones to support a reading of Descartes’s philosophy.     

初中生学习化学兴趣的发展趋势

针对目前初中化学教学中学生因缺乏应有的学习兴趣而导致学习动力不足和影响其个性和谐发展的问题，运用现代教育学、心理学的理论，结合初中生的心理特点和化学学科特点，提出把初中生学习化学兴趣提到学生稳定的个性心理品质上来研究，是符合马克思主义关于人的学说和现代教育心理学理论以及初中化学教学实际的；初中生学习化学兴趣的形成和发展是一个立体发生的过程，其纵向趋势为：直感兴趣→解析兴趣→探索兴趣；其横向品质为：指向性、持久性、广泛性和有效性，初中生学习化学兴趣水平的提高应当在有效的教学中进行
