The philosophical implications of "chaos" cannot be grasped without clear understanding of such concepts as "determinism", "non-linearity", and "predictability". Beginning with Laplace's classical statement of determinism and predictability, I will sketch Maxwell's and Poincaré's modifications of the statement and their awareness of the significance of nonlinearity. Then I will briefly touch upon what may be suggested by the study of chaos for clarification of the notion of complexity; and, finally, contend that the computation for the study of chaos can be regarded as a kind of inductive basis, which provides the affinity of mathematics and natural sciences, on the one hand, and the continuity of traditional sciences and studies on chaotic systems, on the other.
