Soft eggplants may mean that they are past their prime. If so, and they are just a little soft, they can probably still be used in cooking, although they might be more bitter. If mushy, discard. Certain diseases can also cause fruit to soften before they would normally be ripe. Check for other signs of disease, on stems, leaves, and the fruit itself (mottling, watery areas, yellowing, mold, wilting etc.)
