“The intentionality peculiar to motor activity is not a search for truth but the pursuit of a result, whether objective or subjective; and to succeed is not to discover a truth.”

Aphorism 19
Novum Organum (1620), Book I
Context: 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.

Context: As in reply to the skeptic or agnostic, who asserts in despair that there is no absolute truth. The dialectician retorts: Then at least your own assertion must be absolutely true. There must be some absolute truth, for you cannot assert that there is none without self-contradiction. As in Descartes' case, the doubter is reminded of himself. There, in his own assertion, is a certainty from which he cannot escape.
This turn of thought which reminds the enquirer of himself, we shall call the reflexive turn. It reappears in all discoveries of the Absolute. It is clinching--but is likely to disappoint, even as Descartes' result disappoints. For the skeptic finds that he also was in search of objective truth: and that the absolute truth of his statement is irrelevant to his quest. Whence his skepticism toward objective truth remains unanswered.

Context: Intellect is to the people and the people's Force, what the slender needle of the compass is to the ship — its soul, always counselling the huge mass of wood and iron, and always pointing to the north. To attack the citadels built up on all sides against the human race by superstitions, despotisms, and prejudices, the Force must have a brain and a law. Then its deeds of daring produce permanent results, and there is real progress. Then there are sublime conquests. Thought is a force, and philosophy should be an energy, finding its aim and its effects in the amelioration of mankind. The two great motors are Truth and Love. When all these Forces are combined, and guided by the Intellect, and regulated by the Rule of Right, and Justice, and of combined and systematic movement and effort, the great revolution prepared for by the ages will begin to march. The Power of the Deity Himself is in equilibrium with His Wisdom. Hence only results HARMONY.

The Hemoglobin Molecule, Scientific American, <B>211</B>, 65-76, November 1964. This comment refers to the appeareace of the low resolution structure of hemoglobin, which Perutz was instrumental in elucidating in a heroic effort that spanned 1937 to 1959. In the course of this work, Perutz and his co-workers developed many of the techniques that are used to this day to determine the three-dimensional structures of macromolecules.
