_Histoire d'un Savant_, 284. Douter des verites humaines, c'est ouvrir
la porte aux decouvertes; en faire des articles de foi, c'est la

[71] We should not only become familiar with the laws of
phenomena within our own pursuit, but also with the modes of thought
of men engaged in other discussions and researches, and even with the
laws of knowledge itself, that highest philosophy.--Above all things,
know that we call you not here to run your minds into our moulds. We
call you here on an excursion, on an adventure, on a voyage of
discovery into space as yet uncharted.--ALLBUTT, _Introductory Address
at St. George's_, October 1889. Consistency in regard to opinions is

(Conclusion). Vice was obliged to retire and give place to virtue.
This will always be the consequence when truth has fair play.
Falsehood only dreads the attack, and cries out for auxiliaries. Truth
