Truth, Falsity, and a Tomato

So I was working on my philosophy homework this afternoon and I came across an interesting quip about the necessity of truth and falsity. That got me thinking. It seemed to make sense to me that in order to progress in anything, certain things need to be recognized as false and new truths emerge.
Take a tomato plant, for example. First, we see the stem and some leaves. That manifestation is quickly proven false (in terms of the plant's final "truth") by buds appearing. Now the tomato plant is realized as more than just a stem and leaves. Next, our latest image is once again falsified by the appearance of flowers. We are progressing and moving closer to the truth. Finally, the fruit appears and the ultimate truth of the tomato plant is manifested in a stem, leaves, and a delicious, spherical, and red hamburger condiment.
So the progression of false to true got me thinking about today's trend of "your own truth". Finding what's true for you may be beneficial for your own individual realization but on the whole it seems like we may just be changing our ideas about what the flower bud looks like without ever admitting that a flower lays in its future. If we were to admit such a thing, the flower bud, no matter how hard it had worked or how beautiful and pure it appears, would have to disappear and make way for its successor, a greater truth. Maybe you remember that when you were growing in your adolescent years, your body ached. It was painful, sure, but through it you grew into a full size adult. Many of us have been in relationships with people where there has been friction and arguing, but we know that (if we have survived) those relationships are the strongest. It seems to be almost a universal principle that we're ignoring: conflict happens and can be resolved for the better and that truth is not always easy. So I say we need to get rid of this "no pain" mentality that society seems to have taken on and start searching for truth, not morphine.
