Freethought holds that individuals should not accept ideas proposed as truth without recourse to knowledge and reason, so they build their understanding based on things that are very likely to be true or have strong arguments for their truth, or in other words, logical! Honestly, I agree with this so much! All other arguments, we should be skeptical about, of course, to a healthy extent, of which you will have to reasonably determine what strength is necessary for truth... if at all.
