But though the Folly of such Pretenders cannot be avoided, we must not therefore reject the sober and the judicious Observers. It is better sometimes to indure Vanities, than out of too much Niceness to lose any real Invention. We ought to do with Philosophical Works, as Ministers of State with Intelligence. It is the wisest Course to give Incouragement to all, least by shewing ourselves too scrupulous of being impos'd on by Falshoods, we chance to be depriv'd of the Knowledge of some important Truths.

The next Particular which I resolv'd to handle, is the Advantage of Experiments in respect of Physic.
