Man likes to think logically, although it is immensely hard to stay consistent while thinking. If we fail to stay consistent in the intellectual sphere, how can we expect to be so on the moral plane? Almost impossible…
In Indian culture the beginnings of logic reach back to mythical times. Well before Buddha appeared, advanced schools of logic already existed, and, interestingly, they did not merely analyse methodical thinking or the technique of argument, but sought to harness man's intellectual faculties for the attainment of his spiritual goals. Put plainly, ancient logical thought may have had spiritual-metaphysical aims.
One of the earliest sources is known to us only from allusions; The Rulebook of Logical Thinking has not survived. All we know is that the great heroic epic, the Mahabharata, mentions a reformulation of it. The political scientist Chanakya, active around 300 BC, names logic among the schools of thought of his age.
From the references we know what subjects The Rulebook of Logical Thinking dealt with. Among other things, with the question of matter and spirit, the purposefulness of nature, the multitude of souls, their relations and their inactivity, and the unfolding of the categories.
The rulebook declared that false knowledge and contentment are serious obstacles to spiritual progress. The former is self-evident, but how does contentment become an obstacle? Logically, we might think that contentment is one of the practices of yoga, one of the pleasing results of the spiritual process…
Of the five kinds of faulty, false knowledge, i) simple ignorance is the first, and it is like darkness. ii) The egoistic sense of self may be identified with illusion, but iii) the attachment that springs from it is comparable to a profound mirage. Where there is attachment, iv) aversion or loathing is inevitable, a truly hellish state of consciousness, and only v) misconceived self-love is more fatal, likened to the deepest circle of hell. No doubt these errors and failings hinder enlightenment. But contentment?
If the aim of human life in general, and of the science of logic in particular, is the attainment of salvation, then the following kinds of contentment may be real obstacles.
i) Some claim there is no need for effort, because nature brings salvation automatically, and yet it is held that a cart does not move on one wheel: divine grace and human effort are both needed. Others say ii) there is no need for meditation, that renouncing family life is enough. Meditation would be precisely one of the hermits' chief practices, for, as opposed to the pragmatic practices of family existence, they can offer sacrifice on the mental plane. According to the procrastinators, iii) there is no need to hurry, for salvation will come in its own time, while the fatalists claim that iv) salvation is a matter of fate.
The man entangled in material existence is also held back by cares that grow into kinds of laziness, for example i) the enervation that springs from the cares of making a living. The answer to this is that God becomes action in man… Laziness may also spring from ii) guarding wealth already amassed, or from iii) the natural wearing out of things, the former rather in the form of contentment, the latter as a kind of despondency. The reflective man realises that iv) desires, forever arising anew, lead only to discontent, and so he does not act. The cure for this would be selfless action, while the morally contemplative man sees that v) one person's gain is won at another's loss, and so he does not act. In the world of give and take such a levelling out can indeed be found, but the actions of the selfless and dutiful spiritual man serve the universal good.
Thoughts thousands of years old still seem valid today…
