Cogent reasoning is different from deductive reasoning because the premises and conclusions of cogent arguments are determined to bemost likelytrue and to lead to conclusions that are probably true. A cogent argument is one for which there is good evidence for the premises and conclusion, and thus is considered plausible or likely.

Analyze their arguments and determine if you also believe them to be cogent. Explain your reasoning. In addition, is there a way to make the argument a valid,deductiveargument? Why or why not?

Cogent argument:

1. Goldfish have fins.

2. Fins are used to swim.

3. Therefore, goldfish can probably swim.

All goldfish do have fins. Fins are primarily used for swimming, but can also be used to regulate temperature or simply as ornamentation. Even though fins have other uses, goldfish, more likely than not, can swim.
