Science is simply common sense at its best, that is, rigidly accurate in observation, and merciless to fallacy in logic.

Science is nothing but trained and organized common sense differing from the latter only as a veteran may differ from a raw recruit: and its methods differ from those of common sense only as far as the guardsman's cut and thrust differ from the manne

Science is organized common sense where many a beautiful theory was killed by an ugly fact.

From the dawn of exact knowledge to the present day, observation, experiment, and speculation have gone hand in hand; and, whenever science has halted or strayed from the right path, it has been, either because its votaries have been content with mere unverified or unverifiable speculation (and this is the commonest case, because observation and experiment are hard work, while speculation is amusing); or it has been, because the accumulation of details of observation has for a time excluded speculation.

The cradle of every science is surrounded by dead theologians as that of Hercules was with strangled serpents
