What are the strengths of a priori arguments?
+ Not based on senses that can deceive us
+ No need to collect sensory data
+ Mathematical formula and logical

true
+ No empirical evidence against
What are the weaknesses of a priori arguments?
- If we deny the premises the conclusion fails
- Can’t take into account empirical evidence for
- Is it possible to argue from the unknown to the known?
- Need senses to survive
- It may only be possible to know a priori definitions

What are the weaknesses of a posteriori arguments?
- Our senses can deceive us
- Conclusion still only probable
- Must make a leap of faith to conclude God exists
