Dear Professor Silva,
At the moment at least, I cannot locate any passage where Peirce would have used exactly the words you cited. That line ("Logic is the ethics of thinking") is found in T. L. Short’s book on Peirce’s theory of signs, but I suspect that what you have in mind is a statement that Frank Ramsey reportedly attributed to Peirce (“logic is the ethics of thinking, in the sense in which ethics is the bringing to bear of self-control for the purpose of realizing our desires”). I. A Richards mentions it in a couple of places, but without providing a source. I has occasionally been repeated in the literature – attributed to Peirce, but again without citing the original source.
As far as I can tell, it is a paraphrase rather than a direct quote – but it is quite possible that the exact phrase can be found in somewhere Peirce’s vast corpus, much of which has not been published. In any case, the following quotes (especially the second, from an unpublished manuscript) capture the sentiment:
· Logic is the theory of self-controlled, or deliberate, thought; and as such, must appeal to ethics for its principles. It also depends upon phenomenology and upon mathematics. All thought being performed by means of signs, logic may be regarded as the science of the general laws of signs. (Syllabus of a course of Lectures at the Lowell Institute, EP 2:260)
· The purpose and utility of logic […] lies in its final achievement of a methodeutic for the guidance of thought; and from this point of view logic is the theory of the self-control of thought in order to realize its intention, which is truth. So regarded, logic may be called a special kind of ethics, if by ethics we mean the theory of the self-control of conduct in order to realize a deliberately adopted purpose. For inquiry is only a particular kind of conduct. (On Classification of the Sciences, MS 602:8)
I copied these from the on-line Peirce quotation dictionary that I am compiling; you will find it here: http://www.commens.org/dictionary.
I hope this is of help.

Dear Marcus,
This phrase occurs in Husserl's Logical Investigations, vol 1, pg 43. "He [the logician] aims not at a physics, but an ethics of thinking." The first three chapters of LI are much concerned with the idea of logic as a normative science, which be of use for your project.

Hi Marcos
Arthur Prior’s book (Oxford: Clarendon Press, 1956) is a good place to start for relevant reading on the general topic.
All the best,

Dear Marcos,
The exact reference for the sentence you quoted
is page 63 of T.L. Short., 2007. Peirce's Theory of Signs.
Cambridge: Cambridge University Press. As far as I know, Peirce did not wrote
"Logic is the ethics of thinking" but, to be sure, he conveyed
something akin in The
Essential Peirce Vol 2, page
42: "For if, as pragmatism teaches us, what we think is to be interpreted
in terms of what we are prepared to do, then surely logic, or the doctrine of
what we ought to think, must be an application of the doctrine of what we
deliberately choose to do, which is Ethics."
Best

Dear Marcos,
I received your email to PHILOS-L. I am working on my thesis about reasons for action. However, naturally these debates take me to questions about reasons in general too. One paper came to my mind regarding logic. Attached you may find it. I enjoyed reading it. Hope it be useful.
Yours,
Seyyed Ardakani

Seu email inicial passou batido aqui, no entanto, eu teria muito interesse prosseguir a conversa sobre ética e lógica, especialmente sob a perspectiva de Peirce.
Espero ter ajudado.
um abraço!
Juliana
