Despite claiming unbelief in God or any higher power that may have designed or created the world and all that is in it, modern scientists often write and speak of chance as some kind of being or force that can cause things to happen. In one breath they push the evolution agenda and in the next they say that creatures were “designed” with specific traits. In this classic book, R. C. Sproul and Keith Mathison call the scientific world to employ logic and clarity in their discourse, to leave the word chance as an abstract concept to describe mathematical possibilities rather than an ontological being that can actually causechange. This expanded edition includes a new chapter dealing with the most recent attempts to defend irrational scientific statements. Two new appendices answer critics and review other literature on scientific discoveries that support belief in a Creator God.
