Very helpful indeed. Especially in my case when there seemed to be a printing error in my book: Introduction to Logic from Iving M. Copi & Carl Cohen, where the disjunction was written to be true when both premises on a table where false. That, in the book messed up my head lol, but your videos put me back on track. Thanx again Dr.
yes i agree with the other cements i have learned more from these videos in ten minutes then sitting in class for 2 hours!!! my professor is from UK and uses stupid statements that don't make sense in the USA and doesn't actually provide enough detail to understand the scenario he is describing.
In the course I am presently taking we are using the book "Critical Thinking" by Jamie Carlin Watson and Robert Arp, have you had the chance to read it? What other materials would you recommend; which can be used with this book to sort of reinforce a better understanding of Logic?
Correct me if I'm wrong. If A is false and B is false, therefore the argument is safe, like in conditional. As long as there are no true facts happening in both conditional and biconditional, there won't be any reason to set a condition, right?
An example of bidirectional that might help: Statement A: I am very rich Statement B: I have 1m $ Statement A: False Statement B: False I am not rich and I don't have 1 m$ and these 2 statements make completely sense therefore the result is: True 2nd example Statement A: True Statement B: False I am very rich and I don't have 1m$ And that doesn't make sense, there the final result is: False 3rd example: Statement A: False Statement B: True I am not rich and I have 1m$ and that doesn't make sense therefore the final statement is : False Last example 4: Statement A: True Statement B: True I am very rich and I have 1m$ therefore the final result is: True
