The concept of true premises sometimes bothers people. We livein a relativistic world. How do I know a particular premise is reallytrue? We can easily sidestep the sticky epistemological issues bybeing pragmatic about what we mean by "true." Truth iswhat is generally accepted to be true or accepted to bedemonstrated. Some premises are unproblematic for all but thediehard relativist philosopher. If I say my shirt is red, you cancheck my shirt to see whether I'm lying. Other statements areharder to verify. Basically, if others "buy" a premisethey are judging it to be true. And if not, if they don't accepta premise, what happens? Just what you'd expect--you need to findother premises that support the one in question, and buildan argument that proves it, and hopefully those premiseswill be common knowledge and acceptable. The bottom line is, nomatter how "true" a premise is in actual fact (whateverthat means) if the receiver of the argument doesn't think it is,the argument won't get off the ground. And, sometimes when newinformation becomes available, an argument that used to looksound doesn't look so good anymore.
Because of cooperative nature of this enterprise it issurprisingly difficult to devise arguments that students will becomfortable labeling sound or cogent. After all, with a writtenand graded argument you can't engage in the questioning andproving premises I just described. For that reason you will notbe judging whether the arguments are sound or cogent for yourassignment. But do keep in mind that doing so is the pointof the whole project of logic.

The EECS Director of Undergraduate Student Instruction, Christopher Hunn, and the EECS Director of Undergraduate Affairs, Antoine Davis, have won 2020 and 2021 Advising and Student Services Awards. These awards are presented by the UC Berkeley Council of Advising and Student Support to "recognize the positive and innovative impact our recipients have on student learning, engagement, and belonging on the Berkeley campus." Hunn won an Equity Champion Award for coaching TAs, undergraduates (especially CS Scholars and CS Mentors), graduates, staff (including student services personnel), and faculty "with evidence-based practices that have increased student engagement, success, self-efficacy, and belonging." Davis won an Outstanding Advising or Student Services Administrator, Director, or Manager Award for supporting and strengthening his staff team and the EECS and CS undergraduate populations, particularly during the pandemic, with his unique blend of humor and calm positivity. "His relaxed approach fosters an environment where we are able to engage in self-reflection and open-mindedness toward each other and our students." The winners will be celebrated at a virtual ceremony on December 15th.
EECS Prof. Emeritus Lotfi Zadeh (1921 - 2017) is being honored with a Google Doodle feature today. In 1964, Zadeh conceived a new mathematical concept called fuzzy logic which offered an alternative to rigid yes-no logic in an effort to mimic how people see the world. He proposed using imprecise data to solve problems that might have ambiguous or multiple solutions by creating sets where elements have a degree of membership. Considered controversial at the time, fuzzy logic has been hugely influential in both academia and industry, contributing to, among other things, "medicine, economic modelling and consumer products such as anti-lock braking, dishwashers and elevators." Zadeh's seminal paper, "Fuzzy Sets -- Information and Control," was submitted for publication 57 years ago today. 2ff7e9595c
