I know that many will call this useless work. Though I may not, like them, be able to quote other authors, I shall rely on that which is much greater and more worthy-on experience, the mistress of their Masters.

If others would think as hard as I did, then they would get similar results.

Experience is never at fault; it is only your judgment that is in error in promising itself such results from experience as are not caused by our experiments. For having given a beginning, what follows from it must necessarily be a natural development of such a beginning, unless it has been subject to a contrary influence, while, if it is affected by any contrary influence, the result which ought to follow from the aforesaid beginning will be found to partake of this contrary influence in a greater or less degree in proportion as the said influence is more or less powerful than the aforesaid beginning.

I believe there exists, & I feel within me, an instinct for the truth, or knowledge or discovery, of something of the same nature as the instinct of virtue, & that our having such an instinct is reason enough for scientific researches without any practical results ever ensuing from them.

Science is the century-old endeavour to bring together... perceptible phenomena... through systematic thought.

It stands to the everlasting credit of science that by acting on the human mind it has overcome man's insecurity before himself and before nature.
