Now we will be introducing new symbols so that we can simplify statements and arguments. P •K v= 'or' George or Chelsea will be at the meeting tomorrow. So, for communicating the rest of the semester we need to make a few substitutions. We saw that we could represent the patterns of common fallacies and simplify them in symbols. The process is very similar. Chapter 12 will introduce some controversy and new thinking on this process. Students will often comment that their heads are spinning after reading C7. (S, M). Let’s look one more time at the proposition “Roses are red.” If the domain of discourse consists of roses, this translates into predicate logic as \(\forall xRed(x)\). �:�F�$VK�P�!�}�b���Ǝ�������rB��Gm�i�}��5�e7��R��r� ͭ���Xڡd�T�Z�k$���r��쐝2�{�Jk��(��r�[x;ڄ�)r��*8b�b[�-����i�>v�TnZ�x^��)n�5]��M���9� ��XoL���wKL�G�F`Εl�8�B�z)�����N���1_r�� �@�Z�[���ӊ� ��2��%^] ?��s�HRj��h��w( ��f���[_�J8��eue�6�! 3.
