Kazimierz Twardowski wrote a small paper "On the logic of adjectives', published in Polish in 1927, in which he proposed a classification for adjectives like "counterfeit', "purported', "true' and "actual'. Twardowski's classification has been a direct inspiration for the classification of nonattributive adjectives I present here. I thus hope to show that the ideas of philosophers from the Lvov-Warsaw school are still of value today. Without Jan Woleński's work, these ideas would not be well known to us, and we would thus have missed that special Polish variant of analytic philosophy. Modern analytic philosophy needs to have an open mind towards alternative philosophical traditions that are equally analytic in their methods. Philosophers from the Lvov-Warsaw school are not only of historical interest, they are still of value for philosophy today.
