That is, philosophers can assert nonsensical claims with absolutely 0 justification and their work can still be considered genuine philosophy.
Fortunately, philosophers have developed something called: "the burden of proof"; essentially, the principle of the burden of proof statistics that the claimant (the one making a claim) is under an obligation to provide reasonable evidence or supporting argumentation for his or her claims.
Conversely, it also states that the skeptic (the one the claimant is attempting to prove a claim to) is under no obligation to disprove a positive proposition until, and only until, proper evidence has surfaced.
Moreover, I would argue that the argument from ignorance is valid in many cases. For example, imagine you are to claim that 500 men will destroy the United States tomorrow; tomorrow passes, and the United States has remained intact. The absence of evidence, in this case, can safely be said to be evidence of absence.
Most of the time a big part of philosophy is to see with subjective eyes, it involves reason which operates from an inner level, dare I say intuition? See this is where I get kinda ticked, people disregard anything that seems too far out of the realm of facts and science. I mean the basis of philosophy is analyzing your ideas relative to life. Your relationship towards life doesn't come from outside of yourself.
