| Cytat |
Dobre pomysły nie mają przeszłości, mają tylko przyszłość. Robert Mallet
De minimis - o najmniejszych rzeczach.
Dobroć jest ważniejsza niż mądrość, a uznanie tej prawdy to pierwszy krok do mądrości. Theodore Isaac Rubin
Dobro to tylko to, co szlachetne, zło to tylko to, co haniebne.
Dla człowieka nie tylko świat otaczający jest zagadką; jest on nią sam dla siebie. I z obu tajemnic bardziej dręczącą wydaje się ta druga. Antoni Kępiński (1918-1972)
