An adamant, dogmatic attitude is one route immature minds take in their quest for security. A well-informed person does not need to be dogmatic in order to feel secure. A tendency to speak dogmatically is characteristic of intellectual immaturity and an immature faith. Such faith is probably better than no faith at all, but it can trip and fall when it stumbles onto evidence it is unable to explain away or controvert. It is inherently weak and defenseless.
Blind faith is just as much a handicap as physical blindness.
There is no virtue in ignoring or denying observed and verified facts, whether of paleontology, geology, or theology. Misconceptions as to what the Bible actually says may become as serious roadblocks in a dialogue between science and religion as misconceptions as to the observed phenomena of the natural world. There is as much danger in misreading the Bible, and thereby being diverted from the strait and narrow pathway to truth, as there is in misreading the fossil record in the rocks. As a result he abandoned the Bible account of the origin of species. A misinterpretation of the data of revelation, like a misinterpretation of scientific data, can be just as fatal both to faith in the revealed Word and to truth about the natural world.
