Abstract
The research "From Pure Quantity to Quantum in Hegel's Science of Logic reconstructs the 1st chapter of this session that poses the problem of passing from Quality to Quantity. The dialectic of being for itself led to the quantitative unit that is, initially, pure immediate quantity in relation to itself ; the result of this process brings immanent moments of attraction and repulsion that are now continuous and of discrete magnitude these two moments contain each other reciprocally forming an inseparable unit, that is, quantity is an uninterrupted process of the ones. However, the limitation of quantity describes that both in continuity and in discretion there is a limit that leads to the quantum. Then, we briefly present the problematization of the quantitative being and mathematics, in order to show the relevance of making quantity explicit in Hegelian logic.
