Final answer:
Rationalists believe that genuine knowledge comes primarily through reason, a view best captured in Descartes's statement 'I think therefore I am.'
Step-by-step explanation:
The statement that best describes the view of rationalists is 'Only our reason provides genuine knowledge.' The philosophical stance of rationalism argues that knowledge could be acquired through reason alone, without necessarily relying on experience. This position asserts that reason is the primary source and test of knowledge, and it is manifested in the works of famous rationalists such as Descartes, who coined the phrase "I think therefore I am." Descartes suggested that certain truths can be reached through rational intuition and deduction, like knowing that one plus one equals two.
