Laplace Considers Astronomy A Science Of Observation, Because We Can Only Observe The Movements Of The Planets; We Cannot Reach Them, Indeed, To Alter Their Course And To Experiment With Them. "on Earth," Said Laplace, "we Make Phenomena Vary By Experiments; In The Sky, We Carefully Define All The Phenomena Presented To Us By Celestial Motion." Certain Physicians Call Medicine A Science Of Observations, Because They Wrongly Think That Experimentation Is Inapplicable To It.

Men Who Have Excessive Faith In Their Theories Or Ideas Are Not Only Ill Prepared For Making Discoveries; They Also Make Very Poor Observations. Of Necessity, They Observe With A Preconceived Idea, And When They Devise An Experiment, They Can See, In Its Results,only A Confirmation Of Their Theory. In This Way They Distort Observation And Often Neglect Very Important Facts Because They Do Not Further Their Aim.

The First Requirement In Using Statistics Is That The Facts Treated Shall Be Reduced To Comparable Units.

The Eloquence Of A Scientist Is Clarity; Scientific Truth Is Always More Luminous When Its Beauty Is Unadorned Than When It Is Tricked Out In The Embellishments With Which Our Imagination Would Seek To Clothe It.

The Great Experimental Principle, Then, Is Doubt, That Philosophic Doubt Which Leaves To The Mind Its Freedom And Initiative, And From Which The Virtues Most Valuable To Investigators In Physiology And Medicine Are Derived.
