But lest I should mislead any when I have my own head and obey my whims, let me remind the reader that I am only an experimenter.Do not set the least value on what I do, or the least discredit on what I do not, as if I pretended to settle any thing as true or false. I unsettle all things. No facts are to me sacred; none are profane; I simply experiment, an endless seeker with no Past at my back.
There are and can be only two ways of searching into and discovering truth. The one flies from the senses and particulars to the most general axioms, and from these principles, the truth of which it takes for settled and immovable, proceeds to judgment and to the discovery of middle axioms. And this way is now in fashion. The other derives axioms from the senses and particulars, rising by a gradual and unbroken ascent, so that it arrives at the most general axioms last of all. This is the true way, but as yet untried.
Yet truth will sometimes lend her noblest fires, And decorate the verse herself inspires: This fact, in virtue's name, let Crabbe attest,- Though Nature's sternest painter, yet the best.
For Africa to me... is more than a glamorous fact. It is a historical truth. No man can know where he is going unless he knows exactly where he has been and exactly how he arrived at his present place.
By academic freedom I understand the right to search for truth and to publish and teach what one holds to be true. This right also implies a duty: one must not conceal any part of what one has recognized to be true.
