Abstract
Creativity is a developing topic in philosophy in recent years, and it raises a series of challenging questions both in theory and practice for us. In this paper, I will explore creativity with the lateral thinking techniques which aim to solve problems in a creative and lateral way. I will examine the meaning of lateral thinking and its three kinds, the conceptual lateral thinking, the emotive lateral thinking, and the diagrammatic lateral thinking, trying to find out how the space of possible solutions is affected by lateral thinking, which separates the creative from the problem-solver.
